Sorry I got it now.
On the other hand, while I'm not a teen (by a long shot), I do find facebook more restrictive in terms of the things I feel I can say. Somehow twitter is more anonymous, despite being more public. On facebook I get the impression that people are more likely to pay attention to my ramblings.

It's "SMS" + links + pictures + video
Now that isn't in itself a reason why they wouldn't choose FB when they got to a little older but it's sure something for Twitter to think about IMO.
