SportsBlogs Nation recently signed an advertising agreement with Federated Media. I don't know quite how to put this, but they're kind of a big deal. Maybe. I dunno. They did mention this site specifically in the press release, though, so they're A+ in my book.
Anyways, they've asked all of the blogs on the network to have their readers take a quick survey. Nothing personal, really, just age, income, internet surfing habits, and sexual history. Well, that last one isn't specifically asked for, but there is a space for additional comments. You can do the math.
