trolls...?

just learned about internet trolls, and just what exactly it is they do. why would a person want to disrupt a bunch of people talking about something as menial and insignificant as wedding dresses or motorcycle preferences? I think it hilarious that some idiots can't stand to let a Usenet group have a conversation about whatever it is they choose to talk. so are they Trolls? definitely. And they definitely all seem to be living under a bridge... or their mothers' basements.
