MIT Weblog Survey

Cameron Marlow is the PI for this study. He's written some neat stuff on information diffusion and the way blogs work. I got a very quick chance to meet him at ASIST last year. Anyway, this is for his dissertation, so if you have a chance you might want to participate. It's more scientific than the traditional surveymonkey what with a human subjects review, etc., but that shouldn't be too surprising for those of you who are familiar with social sciences research.
Update 6/30: It just occurred to me that the PI might be using the survey as a meme to study information diffusion :) He only contacted A-listers directly, and now lots of us with >100 subscribers are responding... makes you go hmmm. At any rate, it's still going so you can participate if you haven't already.
