I have a couple of nephews that have grown up wired. They've been using instant messaging for years and now one of them is planning to start a photo blog.
If you think online communication/social software is growing now- wait until these kids start making business decisions.
I thought this quote from a teen was key:
She doesn't have cable TV, but if she did, ''pretty soon I'd just get bored of it,'' she says. On the Internet, ''you can actually interact with it. TV, you can't really do anything but watch.''
