that truly perplexes me, too. there are myriad threads on FR that i never click on, because i have no interest in them. i don't wonder why others are interested, i am not even aware of how high the post count is on those threads. that anyone even gives a passing thought to why others are interested in anything in particular, perplexes me.
Blows my mind. Same as another list I'm on (not political) and people get all bent when the subject matter strays, like they cannot ignore the thread if they aren't interested.
