CRM Live and OpenSocial?

If you haven't been living under a rock the past week you've probably heard of the new Google initiative OpenSocial. OpenSocial is not a new social network, it is a set of common APIs that application developers can use to create applications that work on any social networks (called “hosts”) that choose to participate.

Application builders can build their apps using the OpenSocial API and they can run on any site that support this API. Don't be fooled though that this only applies to social networks. Besides the obvious "social network" participants like Orkut, LinkedIn, Ning, Hi5, Plaxo, Friendster, Viadeo, there's also Salesforce.com and Oracle joining.

Microsoft watcher Mary Jo Foley asks: Should Microsoft join or fight the OpenSocial?

I can imagine Microsoft isn't very keen on joining this Google regulated initiative. However, it would be nice to add some "social networking" apps to CRM Live, that would e.g. integrate with the professional network site LinkedIn or Plaxo.

So what do you think, should Microsoft join?

Update: Humberto from the Dynamics CRM team questions the value of social networks.
