#39 is good enough by me
Well, I know absolutely nothing about the website, but I'm not going to question anyone who ranks The Fruit Blog among the top 50 genetics blogs.
Even aside from the opportunity to brag about my honors, it's worth checking out, because there are some great sites there. Some, like Sex, Genes, and Evolution, John Hawks' Weblog, and Pamela Ronald's Tomorrow's Table, I've been following for a while, but there are a bunch of others in there that look absolutely fascinating.
(Considering they seem to have grouped them by category, I suspect the ranking is meaningless.)
