Re: the entrenched social network... It shouldn't be too hard to create an alternative service / browser extension that will allow people to export their social network? Because then the alternative service could be set to automatically approve any future connection requests from the people previously identified. I'd sign up for such a social-graph-based service that just did individual messaging, group discussions, and events (invitations + pictures). Identity is an issue with social graph export... But on the other hand, doesn't the existence of LinkedIn show that people are willing to re-create their social graph on multiple services?
