One competitor that should be shaking in their boots is Classmates.com Why? Glad you asked. If you’ve never been on classmates.com it’s a great concept but the business model sucks. You can’t really do anything except provide them with personal information unless you’re a paid member. There are some things like messaging that you can use if a message is sent by a paid member. I could be wrong on some of the details here because frankly I don’t ever log in anymore.

At any rate, Facebook could kill them off merely by setting up school memberships. In fact it’s sort of happening on an ad hoc basis already because individuals are setting up year specific groups  for high schools. Clock’s ticking Classmates.
