Of course Facebook will be around in 10 years. How else will the vast majority of the populace make their life look way cooler than it actually is? How else can you have 247 "friends?" How else will people share pointless, often times pathetic, information that no one really cares about? If Facebook were to go away how could people "like" things that they really don't give two craps about (ok, Instagram would work for this). Facebook isn't going anywhere anytime soon so long as people have the desperate need to feel they are known, even if in reality they are not. Perception is reality.
