Bebo now join OpenSocial ...

so big question ... what about Microsoft?

There's also a funny question : what about Facebook?

What, in practice, would it mean for Facebook to join OpenSocial? If your app. takes advantage of FB specific features that don't exist in the OpenSocial API you aren't likely to downgrade it. If it doesn't ... well ...

actually, hold that thought ...

Is OpenSocial going to provide a common catalogue of applications, so as long as you register your app. it automatically appears in the directory of all participating YASNS? Or do you have to register each separately?

What if you widget actually has code to take advantage of features specific to Orkut or LinkedIn? Will it be visible in their catalogues but not Ning's and Bebo's?

C'mon Google let's see ...
