Eowyn:
Not a hijack as far as I'm concerned.
The whole DNA science as it is presented currently by various authorities and sources seems as much a work of "smoke and mirrors" as definitive scientific conclusion. All of which is really to say that, like all "new" scientific studies, it is a work in progress within which there will continue to be controversy, more discovery, evolution, reversals, etc. That seems part of the fun of it all, to me, at least.
So I try NOT to put all my faith into one particular basket of eggs in this matter.
But there are many among us (perhaps even those who would spell that 'amoung') who are quite knowledgeable with the arguments and the present condition of that science. It is the arguments which I find most intriguing...
Meanwhile, the 23andMe results, (while listing 985 autosomal matches of varying degrees), have put me in touch with about 20 to 30 fellow genealogists who are trying to make definitive connections, and a couple of very promising looking 2nd cousin matches - the best two of whom have not yet responded to the invitations for sharing that were sent.
My best expectation for GEDMATCH.com's results is that they will be for folks who are more universally seeking to expand their ancestral knowledge and not merely looking for an already completed, colorful chart or similar novelty. If that turns out to be an accurate assumption, then it will be a helpful result indeed.
Good luck on your quest and happy hunting to you!
