Genetic genealogy...sometimes you just gotta know

Blaine Bettinger, whose blog on genetic genealogy I've been following for a while now, is running a contest to celebrate the blog's one year anniversary. He's giving away a mtDNA or Y-chromosome test from his co-sponsor DNA Heritage.
Blaine's blog is a great way to keep up with everything that's going on in the fast paced world of genetic genealogy. He covers the topic regularly from a variety of perspectives - anthropology, genomics, business, ethics, medicine...
Anyway, I'm entering this contest because I would love to get a free mtDNA test, despite some of the inherent limitations of these kinds of tests.
