At 23andme I have three matches with a 5th cousin (C) who descends from from a couple on my Father's side. This is on one of my paternal great grandfather's line, one of the lines neither of my tested 1st cousins shares with me. Her maternal ancestry has several names in it that are in my maternal ancestry, but they are not traced back to a common ancestor. However, her mother has connections to a county in Arkansas where many of my relatives settled between 1830 and 1860.
When I compare her results to my two first cousins in Family Inheritance: Advanced She has matches with (B). Since (B) is my first cousin through her father, my Mother's brother, and her Mother was from a county that is not in my ancestry nor in (C)'s ancestry, the genetic relationship appears to actually be from (C)'s Mother's side and not from her direct paternal ancestry where she and I have the documented paper match.
This points out two concerns: the paper link is not necessarily the genetic link; and you need to have some way of determining which side of you ancestry the genetic link is on; either full phasing by parent-child groups or by testing your parent's siblings or your grandparents, or selected close relatives, like first cousins, as was done here.

For much of the 20th century, the predominant view of human evolutionary history was derived from the fossil record. Homo erectus was seen arising in Africa from an earlier member of the genus and then spreading throughout the Old World and into the Oceania. A regional continuity model of anagenetic change from H. erectus via various intermediate archaic species into the modern humans in each of the regions inhabited by H. erectus was labeled the multiregional model of human evolution (MRE). A contrasting model positing a single origin, in Africa, of anatomically modern H. sapiens with some populations later migrating out of Africa and replacing the local archaic populations throughout the world with complete replacement became known as the recent African origin (RAO) model. Proponents of both models used different interpretations of the fossil record to bolster their views for decades. In the 1980s, molecular genetic techniques began providing evidence from modern human variation that allowed not only the different models of modern human origins to be tested but also the exploration demographic history and the types of selection that different regions of the genome and even specific traits had undergone. The majority of researchers interpreted these data as strongly supporting the RAO model, especially analyses of mitochondrial DNA (mtDNA). Extrapolating backward from modern patterns of variation and using various calibration points and substitution rates, a consensus arose that saw modern humans evolving from an African population around 200,000 years ago. Much later, around 50,000 years ago, a subset of this population migrated out of Africa replacing Neanderthals in Europe and western Asia as well as archaics in eastern Asia and Oceania. mtDNA sequences from more than two-dozen Neanderthals and early modern humans re-enforced this consensus. In 2010, however, the complete draft genomes of Neanderthals and of heretofore unknown hominins from Siberia, called Denisovans, demonstrated gene flow between these archaic human species and modern Eurasians but not sub-Saharan Africans. Although the levels of gene flow may be very limited, this unexpected finding does not fit well with either the RAO model or MRE model. More thorough sampling of modern human diversity, additional fossil discoveries, and the sequencing of additional hominin fossils are necessary to throw light onto our origins and our history.

467 matches at FTDNA on their Illumina V.3 chip;
1540 matches at 23andme on the Illumina V.2 chip;
1145 matches at 23andme on the Illumina V.3 chip;
2300-2350 matches at AncestryDNA on the Illumina V.3 chip:
Other than known 1st and 3rd cousins I had tested, my closest known matches are at the 3rd cousin level. I have a 2nd cousin match at 23andme who has not answered any invitations in 2 years. I have two predicted 2nd cousin matches at FTDNA who have not replied to emails and do not have pedigrees posted there. I have gotten through the first 27 of 47 match pages at Ancestry.com with many matches having either private trees, very small trees, or no trees. Very frustrating.
I spent this past weekend in Houston at the 8th FTDNA DNA Administrators Conference. I'll post a report later this week.

Background: The Genographic Project is an international effort aimed at charting human history using genetic data. The project is non-profit and non-medical, and through the sale of its public participation kits it supports cultural preservation efforts in indigenous and traditional communities. To extend our knowledge of the human journey, interbreeding with ancient hominins, and modern human demographic history, we designed a genotyping chip optimized for genetic anthropology research. Methods: Our goal was to design, produce, and validate a SNP array dedicated to genetic anthropology. The GenoChip is an Illumina HD iSelect genotyping bead array with over 130,000 highly informative autosomal and X-chromosomal SNPs ascertained from over 450 worldwide populations, ~13,000 Y-chromosomal SNPs, and ~3,000 mtDNA SNPs. To determine the extent of gene flow from archaic hominins to modern humans, we included over 25,000 SNPs from candidate regions of interbreeding between extinct hominins (Neanderthal and Denisovan) and modern humans. To avoid any inadvertent medical testing we filtered out all SNPs that have known or suspected health or functional associations. We validated the chip by genotyping over 1,000 samples from 1000 Genomes, Family Tree DNA, and Genographic Project populations. Results: The concordance between the GenoChip and the 1000 Genomes data was over 99.5%. The GenoChip has a SNP density of approximately (1/100,000) bases over 92% of the human genome and is highly compatible with Illumina and Affymetrix commercial platforms. The ~10,000 novel Y SNPs included on the chip have greatly refined our understanding of the Y-chromosome phylogenetic tree. By including Y and mtDNA SNPs on an unprecedented scale, the GenoChip is able to delineate extremely detailed human migratory paths. The autosomal and X-chromosomal markers included on the GenoChip have revealed novel patterns of ancestry that shed a detailed new light on human history. Interbreeding analysis with extinct hominids confirmed some previous reports and allowed us to describe the modern geographical distribution of these markers in detail. Conclusions: The GenoChip is the first genotyping chip completely dedicated to genetic anthropology with no known medically relevant markers. We anticipate that the large-scale application of the GenoChip using the Genographic Project’s diverse sample collection will provide new insights into genetic anthropology and human history.

440 matches in Family Finder at FTDNA.
1509 matches in Relative Finder at 23andm.com(sharing genomes with 450)
1750+ matches at AncestryDNA. I am slowly working through 38 pages of matches.
Most matches that have an identified Most Recent Common Ancestor (MRCA) are from the Boone, Creekmore, Ball, Moses and Barnes families. I descend from over 20 families of 17th century New Haven Colony.
My ancestry is 95% British Isles and then German, French, Norwegian/Finnish make up the rest. Immigrants settled in Connecticut, New Amsterdam, New Sweden, Pennsylvania, Maryland, Virginia and the Carolinas. Most were here in the 1600s. My most recent know ancestor was transported from Middlesex Gaol to Virginia in the 1760s for stealing cloth.

I now have a DNA match with an individual at 23andme. In comparing our pedigrees, we have one possible connection, Mareen Duval and Susannah. While not a definitive match, we could have other Maryland ancestry in common, I do think this does support the identification of Susannah as a daughter or other close relative of Benois Brassieur.
That link leads to Presidents Barack Obama and Harry S. Truman, former Vice President Dick Cheney, and to entertainers Ellen Degeneres and Robert Duval.

This will be the sixth autosomal DNA test I have had. I have already tested with the Coriell Institute, Family Tree DNA, 23andMe, and DeCode Genetics. I was also tested by Sorenson Molecular Genealogy Foundation but the autosomal results were never released.
I do not expect to have any new ethnicity results, but I do expect to have many more verifiable genealogical connections tied to the pedigree trees at Ancestry.com.
So far I have similar results from Family Finder at FTDNA and Relative Finder at 23andMe with 15 verified connections in each where I am sharing genomes with around 400 people in each database.

to the Ashkenazi "Jewish correction" used by 23andme and how it keeps
Ashkenazi Jews from seeing their non-Jewish cousins. Because of the
many intermarriages among European Jews the genetic relationship
predicted is often greater than that expected from the documented
genealogical relationship. These predicted higher or closer relations
push out the genetically smaller but documented higher genealogy
Many of the Ashkenazi cannot determine the relationships being shown
since the predicted range is too close and their pedigrees are not
detailed enough to make the connection. Below I'll give a non-Jewish
endogamy example where the relationships can be determined.
Last night I received a predicted 2nd cousin at 23andme. The per cent
of shared DNA is 3.02 in 13 segments for 226cM. He (call him A) is
actually one of my multiple cousins. We (I am B) are 3rd cousins, 3rd
cousins once removed, half 3rd cousins once removed, 4th cousins, 5th
cousins, and triple 6th cousins.
Compared to my multiple 1st cousin (C) they share 10 segments for 151cM.
Compared to my and my 1st cousin's maternal double 3rd cousin once
removed (D) they share 1 segment of 0.9cM.
A is related to B and C on both maternal and paternal lines and to D
through his paternal grandmother.
B is related to A and C on both maternal and paternal lines and to D
on 2 maternal lines.
C is related to A and B on both maternal and paternal lines and to D
on 2 maternal lines.
D is related to A on one maternal line and to B and C on 2 maternal lines.
In all of these cases the predicted relationship, based on DNA shared,
was one generation closer than the documented relationship mainly due
to the high degree of endogamy and the resulting consanguinity.
Now I am waiting for A's wife's results, she is my 3rd cousin once
removed and, yes, we share multiple lines of ancestry. ;^)

Remember that this is an autosomal DNA test and can be used by both males and females to find your relatives from the past 5 generations.
This is a great opportunity to test more family members.
CeCe Moore has also covered this in a post to her blog:

I have 1440 matches at 23andMe and am Sharing Genomes with 402. I have identified 15 relationships with those 402.
The success ratio at both services is comparable at about 4%.
I also have matches at GEDMATCH, but I have not been successful in identifying the relationship with any one there who is not already identified in Family Finder or Relative Finder.
If you are in the 23andMe database, a new feature of Ancestry Finder allows you to compare all of your matches and their matches to see if there are clusters at common locations.

Status of the Sorenson Molecular Genealogy Foundation, SMGF,genetic genealogy DNA Databases and GeneTree
Yes, the databases have been transferred to Ancestry.com. GeneTree will not be continuing; they have stopped taking orders and in the near future www.genetree.com will be taken down. There are not plans to automatically 'convert' GeneTree accounts into Ancestry.com accounts, so GeneTree customers will need to move their information over to Ancestry on an individual basis.
As far as the autosomal database is concerned, our autosomal tests were generated with older technology, making them incompatible with current industry standards. Therefore, they are not included in the autosomal service offered by AncestryDNA. We also don't plan on making them available via smgf.org.
As of today, 1 June 2012, the Y DNA and mtDNA databases are still available at the SMGF site: http://smgf.org/ If you have tested I suggest you go and download your results and your matches. It is my understanding that people will be able to remove their results from the Ancestry.com databases if they so desire.

I opened my Legacy Family Tree database and found Hiram as a son of Samuel Wilcoxon Walker, a brother of my ancestor Jesse Walker, and a son of Renelder Walker and Mary Wilcoxon. I confirmed the name of Hiram's wife and then checked Census records to confirm the pedigree. After that I contacted the submitter and we have confirmed the relationship. This information adds a relationship to the Boone family to the submitter's line.
We have 6 links in the following chromosomes with the assumption being the large link on chromosome 12 comes either from Renelder Walker, or from his wife, Mary Wilcoxon:

Mitochondrial DNA and Y Chromosome Variation Provides Evidence for a Recent Common Ancestry between Native Americans and Indigenous Altaians.
Mitochondrial DNA and Y Chromosome Variation Provides Evidence for a Recent Common Ancestry between Native Americans and Indigenous Altaians.
SourceDepartment of Anthropology, University of Pennsylvania, Philadelphia, PA 19104-6398, USA.
AbstractThe Altai region of southern Siberia has played a critical role in the peopling of northern Asia as an entry point into Siberia and a possible homeland for ancestral Native Americans. It has an old and rich history because humans have inhabited this area since the Paleolithic. Today, the Altai region is home to numerous Turkic-speaking ethnic groups, which have been divided into northern and southern clusters based on linguistic, cultural, and anthropological traits. To untangle Altaian genetic histories, we analyzed mtDNA and Y chromosome variation in northern and southern Altaian populations. All mtDNAs were assayed by PCR-RFLP analysis and control region sequencing, and the nonrecombining portion of the Y chromosome was scored for more than 100 biallelic markers and 17 Y-STRs. Based on these data, we noted differences in the origin and population history of Altaian ethnic groups, with northern Altaians appearing more like Yeniseian, Ugric, and Samoyedic speakers to the north, and southern Altaians having greater affinities to other Turkic speaking populations of southern Siberia and Central Asia. Moreover, high-resolution analysis of Y chromosome haplogroup Q has allowed us to reshape the phylogeny of this branch, making connections between populations of the New World and Old World more apparent and demonstrating that southern Altaians and Native Americans share a recent common ancestor. These results greatly enhance our understanding of the peopling of Siberia and the Americas.*
