A good page was added to the OpenSocial google group today explaining where they are with some important issues (security, naming, roll-out). The good news is, there is more time to get ready (or keep cranking out the Facebook apps).
What’s up with OpenSocial? – OpenSocial | Google Groups: “Do I have to work double time through the holidays to be ready for the OpenSocial launch? At this point it looks like we’ll make a couple more revisions to the API before it’s baked enough for ‘launch’. This puts us into January before the API is ready to be implemented by containers, so expect some early adopters to have a public launch early 2008.”
