When I was a kid, I hated nothing more than having to listen to some blowhard adult tell me "You'll agree with me when you're my age." So arrogant. And as an adult, looking back on all the times this was said to me, I realize so many of their predictions were wrong.<p>Where does this guy get off telling teens "you're going to grow up and use facebook, and you're going to like it".<p>It wasn't that long ago when myspace seemed unstoppable. Facebook could die off just as easily. We can't know for sure.
