I snoop because it's a good trend forecaster. When there's drama or lulz to be had, obviously a lot of people will be visiting a specific thread. That or sometimes it points out a thread of interest.
Yes, I look in there to see if there's an interesting thread too. The guest bots come up with some good old ones, sometimes, too.
Don't you hate it when it says someone is posting in a thread, then they must decide not to post, and it's not there....but you've waited for their little gem to arrive, but they've thought better of it and not posted after all.
