Match statistics from FTDNA, 23andme and AncestryDNA

As of today I have:

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.
