Just when we thought that Facebook was the only social network in town, Google is potentially changing the rules of the game with Open Social.
In network terms, Google is saying the social networks are currently too closed and is suggesting that through common APIs (common software code) we can make them all potentially speak to each other. Very interesting move. Anything which links networks together makes it theoretically more powerful and dynamic and of course interesting in terms of communication flows. John Batelle gives initial insight on this and his blog will be worth following over this in the coming months. Potentially very significant for the PR industry as theoretically would allow common approaches to social network campaign/announcement rather than as currently which would require separate approaches to Facebook and MySpace networks.
