John:

I am a genealogist. 30 years. Certified by the Board for Certification of Genealogists in Washington D.C. I beg to differ with you and most vehemently at that. I want SNP testing so bad that since no one else was doing it I founded two corporations that can test SNPs. On a personal level, thanks to our lab (an my geneticist partner who read the electropherograms) I know I am R1b1c and with haplotype evidence likely aboriginal English (grandfather born there); and my other grandfather (via testing my uncle) M17 and confirms the Shetland Islands "Norwegian" traditions in our family. There are those who just "don't get it" any more than they don't understand why I would want to known my mtDNA subclade. You can't please everyone - but please don't denigrate those of us genealogists who took off the blinders long ago and have a wonderful wide angle view of the genetic landscape.
