@ChocolateReigns – Facebook has over a million people online at any one time. I know that. But 350 mil active members I doubt its that much, i know alot of them accounts would be inactive or dupes.
Probably not a lot. Likely fewer than Answerbag, where I came from, which in turn likely has fewer than Yahoo! Answers (where I was before going to Answerbag); and yet, I’m often seening the same people in Yahoo! Answers. Also note that while Wikipedia articles exist for Yahoo! Answers and Answerbag, none exist for Fluther.
