>Got it, so make a better group service and bring everyone to that.
You are going to need significant value-add to convince people to bootstrap their identities and social graph all over again. Snapchat did it by piggybacking on "people who have each other's phone numbers." Tumblr did it by not doing it - the social network is deliberately separate, and you have to be much closer to someone for them to tell you their Tumblr URL.
I will never use your service if I have to sign up, confirm my email address, add friends, convince them to sign up and actually check it, etc. Decentralization is the surest way to destroy user experience. Facebook already knows me and everyone I know in real life. Why would I not just use it?
