Actually, everyone I know who has a blackberry is young. The reasons are varied - one of the big reasons is that most of the cell companies offer plans where facebook, twitter, and BBM do not count against your data plan or you don't actually need a data plan to use these services. Again, the same companies often charge for txt messages but not for BBM.

It's mainly because BBM is a non-threatening way to give out your contact information. You can add a guy to your BBM list, chat with him and then if you find out he's a crazy you can block him. The person can't constantly txt you or call you back like with your cell phone number. It's brilliant for us ladies. :)
