Google+ API for Developers
If you are like me and searching the API of Google's new social platform Google Plus before searching for an invite, I have one bad and one good news for you.
Bad news; there is no public API for Google+ yet and there is no estimated date for it as well!
Good news; there is a private mailing list for the developers who are planning to integrate Google+ to their projects. Use https://services.google.com/fb/forms/plusdevelopers/ link to sign up for up to date posts about Google+ API.
