My personal view on this (take or leave it) is that unless you are being backed by some very rich investors, you don't have a hope of gaining any sort of traction here. I do like the 'address book' concept, though, and have toyed with similar ideas previously - a place for everyone to have a single page 'profile' with links out to their real social accounts etc. But in this age of privacy and tracking awareness, I don't think the average internet user will want to put all their contact info in one place. The real problem with Facebook is that for most people it's frictionless... it's really easy for people who use it to chat and share with other users. For them, there's no real compelling reason to switch platforms. Asking them to at this point is like trying to sell a mobile phone on a new network that can't dial other networks.
