This is a really interesting Q&A about OpenSocial. We're trying to decide right now if we want to integrate it into our project, <a href="http://konnect.me" rel="nofollow">http://konnect.me</a>, but I am not sure it is gaining the traction.<p>Facebook not being on board the OpenSocial bandwagon is unfortunate. Things would be much better for the industry if they weren't doing their own proprietary thing with Facebook Connect. Of course, if I was in their position, I'd probably do the same thing.
