I hope this is and the obvious interest of twitter and facebook to get in on this action represents a crack in the closing web. And in some sense, it always seemed like that's what G+ was all about: a moat to make sure they'd keep get/access to all the information that was flowing into closed social networks. Being included in search results is a powerful incentive. The next step has to be open APIs, though, right? I should be able to add social signals outside of G+ and other closed social networks.
