The tech docs of OpenSocial are available now, so I had a chance to check it out. Even though the API’s aren’t 100% finalized yet, it looks great. Things are really changing with this: I was dreaming of someone doing this ever since Facebook did their opening up thing, and now Google has, and they’ve done a great job so far. Only nitpick: remove the references to Google gadgets throughout the docs.. if this is Open, then you shouldn’t refer to your own systems so much in the documentation.
