Just stay clear of the Adverts section then.
Anyway, I disagree. There are some fascinating, important and complex questions on their sometimes- my favourite is "which advert features the song they're tasty, tasty, very, very tasty" which crops up every few weeks.
My gripe is about the green newbies who ask questions about either bank sort codes, Mail on Sunday quizzes or last minute homework (where the answers are freely available via google) and never acknowledge our replies.
