How about a simple rule of thumb: you have to actually meet or talk with a "facebook friend" (every month or more) or else delete/unfriend them.
If after a few months you have zero "facebook friends" nuke the account.
Internet updates are no substitute for good old meat space.

Tell me you're young without telling me you're young. Friendships are more than just meat space meetings. Children, moving countries, crazy work schedules are all reasons that can prevent you being in the physical presence o your friends. Does not seeing them for years at a time make them less friends? No, not to me.
