Google just put up a new
Google+ Platform blog today, to support the growing demand around their new social platform.
Developers have been waiting for the release of the Google+ API, so they can get to work building Google+ applications. While Google did put up a
Google+ developers signup form, there has been no other word about access to the Google+ APIs.
Apparently, todays launch of games on Google+ represents the first wave of developers using the Google+ APIs. Google chose to release the Google+ API to a small number of gaming partners so they could experiment, gather feedback and work the kinks out of the Google+ APIs before releasing it into the wild.
It shows they are starting to allow developers into the Google+ APIs, but I am sure they are prioritizing their partners, and unless your a Zynga or a Popcap, I doubt you'll get early access.
It seems wise of Google to open up access to game developers first, after the major success of the Facebook API platform was around gaming.
