Why are some perguntas on fanpop where they aren't answered for a long time?

It's either the pergunta is stupid, or many people are offline, that's probably why.

The pergunta is dumb and possibly weird..

People probably don't know the answer to the pergunta or just don't want to answer it.

It depends on the pergunta actually.

Not all perguntas will get around to being answered you know. There are several reasons that one might not get answered.

It may be the question, it may be the time it was posted, it may be people being in active, it may be something no one knows, it may be a spam question, several reasons.

Cool story bro.

Probably Because They Don't Know The Answer,Someone Else Gave Exactly The Same Answer,They Don't Have An Opinion Over The Subject Or The Same pergunta Has Been Asked Over And Over Again !!!!

People are lazy that's why.

because its retarded and stupid thats why pretty obvious

It's possibly a spam like this one:

Some unanswered perguntas are ether nonsense, annoying or not interesting to answer. We had some people trolling and making dumb perguntas in another language like this: أكره الجميع

You blew it people. You weren't supposed to answer this.
Yeah, I'm a hypocrite.

It's sometimes a very inappropriate pergunta to answer, like "what's the size of your pines" or something.
