Biggest use cases for me has been events and groups.

1. Events: Facebook's provides a streamlined experience for hosting events and all my friends use it for birthday parties, house warming and so on.

2. Groups: Facebook's group experience is quite good and I am a part of 4 groups of like minded people that I get to have conversations with quite frequently.

Makes sense in terms of network effects I guess. I wonder where the tipping point is when enough people aren't on Facebook so people go back to other services and / or email.
