Well, that can't be the entire reason they went out because I could name a number of people who made the top 15 and further who I didn't think were anywhere near as social as others. Last season, talonkarrde88 came 3rd without being particularly social.

I guess one of the best ways to work out why people comment is to see whether they still comment when they're voted out, then :P

It could be a bit of both, one or the other, or neither, depending on the contestant.

Ahh, but don't you just love learning about how people see the world like that? I know I do!
