I just got on Google+, and the Circles concept definitely moves the ball forward, but my heart sinks a little at having yet another disconnected social identity. It’s been said before, but it’s worth saying again – social networking needs to be an open, core internet standard like email. You can live on Facebook, Google, Twitter, wherever but your social graph should be independent of any specific service.
I don’t mean this in any (well, OK, a little) granola crunching open source way. Companies should compete to the death on their social graph implementation and added value. But the actual data on who your friends are should belong to you and should be both portable and interoperable. I should be able to friend someone on Google from within Facebook and share core items in both directions. If I get fed up of Facebook I should be able to move my graph and central identity elsewhere.
We’ve got OpenSocial, strangely not mentioned in the same breath as Google+, and Open Graph which is open for things but not people. Also FOAF, XUP, and other possible foundational standards. Of course the barriers here aren’t technical.
Diaspora is an interesting project, but running instances (pods) of a social network is the wrong level of abstraction.
Of course ‘owning’ the graph is tremendously valuable and it’s hard to see Facebook giving this up anytime soon. If Google really don’t want to be evil they should use Google+ to liberate us from the tyranny of walled social gardens. Unless it turns out to be another Buzz or Wave in which case it’s down to us.
