Why do so many people refuse to answer the pending questions on her

Now that seems like a fairly good question to me ;]

wow lol I just had a look at some of the questions you had asked... some pretty... interesting questions there lmao =P

Quite a curious girl now ain't you

because not many people bother to click on unanswered questions?
and they think if it's been asked a couple of days ago it no longer has any relevance...
people never search through questions to see if their question has already been asked, so most people figure why bother wasting time on a question no one will look at...
