Kind of an anecdote, but still interesting, thanks. The question is, then, for how long will Skype be as popular as it currently is? And, will these teens keep using it as they age? If so, will Skype's demographic tend to follow them?

Of course there are a million variables. I mean, AIM is still around, right? But it's no longer the "default" IM system, while a few years ago, it seemed to be (to me, anyway).
