Lol. The people who participate on Yahoo Answers might give YouTube commenters a challenge for the title of Dumbest People On The Internet. I've found that these sites get a little better around this time of year as the 7-year-olds start heading back to school and don't have as much time to fool around on the net.
I seem to have a noticed an increase in forum questions that have a "flavor" I'm not too thrilled with either (and I don't have all that high a bar for what I find is "OK" on a site of this type). I understand diversity in individual preferences/purposes on here. There's a point, though, where there's a fairly universal line among people who use HubPages for reasons other than "fooling around" and socializing with one's own perceived peers. I'm seeing that line crossed more these days, I think.
