Get set to update your tweetdeck, or other multi-social network app. Google+ API is now Public. I of course will be playing with it this afternoon/evening and reporting all the awesomeness. For those of you who have free time you can find more info on the API at http://googleplusplatform.blogspot.com/ and http://developers.google.com/+/api/
Update: Looks like the current release of the API is read-only. Lame, but still it is a start.
