I agree that genealogy must not be forgotten. I belong to a large surname project which has samples for a number documented genealogies. There are still samples which unfortunately are closely related which only have 37 marker results but it seems the focus has shiftedSNP testing.
Is Y DNA testing FTDNA's bread and butter business or the gravy? Either way, I think that they should look at the matches page of the FTDNA personal pages. Carrying the genetic distance cumulatively from the 12, 25, 37 marker panels to the 67 discourages someone who has an odd mutation in the 12 or 25 marker panel so could be missing significant matches because they only show a genetic distance of 4 at 37 markers. The number of people who test, have few matches and drop off the radar is totally unknown if they do not post to ysearch. I have 180 exact 12 marker matches, 88 of them no markers above 12. This percentage does not show up in the 25 or 27 marker panels but I wonder if there are other people like my ysearch WSEQD which only shows 4 25 markers matches and no 37 marker ones, whcih are falling through the cracks.
