I think the whole internet has taking away peoples ability to make decisions.
Maybe aibu is just such a handy thread.
I quite enjoyed a post recently about how much washing people do (sad, i know), but it was interesting to see.
It doesnt matter how unreasonable an aibu post is, people always reply. Its entertaining to say the least :) just look at this thread. 3 pages worth of bitching about pointless aibu threads with a pointless aibu thread.
