How long do you believe Facebook will last?

[Key Holder]

I've quitted Facebook 2 weeks ago for good. I know it has to do with how you use it, but I felt Facebook "made" me expose my information and I hated this; also, having too many "friends" seeing my updates daily and getting flooded by lots of their useless and stupid things... I've gotten REALLY annoyed. Also, I hated to know I was giving free informations to Zuckerberg, Obama etc... I just regret having not leaving Facebook earlier.

Ok, it's no rocket science. Everybody has always known the bad side of Facebook.

But I've noticed people are starting to get bored and are no longer too fond of Facebook. I am pioneer among my friends but they show that they are also annoyed. I am encouraging them to leave.

I have read some articles saying that people in their 20s (I'm 21) and 30s are leaving, so there is some trend.

What do you think? How long until Facebook fades out as a hegemonic social network and becomes like MySpace?
