Once upon a time, AOL was a BBS. What drives a BBS is community. They worked really hard on that aspect and even had messaging between users, forums, games, and more.

Then, they decided they were an ISP instead and started claiming such. People forgot all the other services they offered and focused on the millions of frisbies they gave out.

Facebook is all about community, with messaging, forums, games, event planning, and more.

So yeah, it's what AOL should have been, but wasn't.
