I found out about this from a post over at BoingBoing.
The MIT Weblog Survey
I'm also currently attempting to post an image/link of theirs over in my links column (if only Blogger will cooperate, grrr...).
So if you run a blog, please take the 5 min. to go on over, register and fill out their survey. I have no idea why I'm propounding this other than I like the word 'propound.' It's like the word 'pound' only more.. positive.
