Has anyone else noticed that the average intelligence on Fluther drops considerably on weekends?

I haven’t been on Fluther for very long, but I’ve noticed that there’s quite a jarring difference between the generally thoughtful answers (and intriguing questions) which get asked on weekdays, and the more… Yahoo!ish feeling on weekends. The political balance also shifts farther to the right on weekends, it seems. Has anyone else noticed this? Does anyone have any explanations?

(As an anarchist I am fascinated by voluntary communities and their dynamics. I’ve spent about 15 years experimenting with various sorts of voluntary communities on IRC, for example, seeing how, say, a channel organized on the basis of a constitutional, direct democracy compares over the long term with a channel organized along more laissez-faire, mutualist lines. Fluther is proving to be quite interesting to me, quite apart from the actual questions and answers.)
