MySpace boarding the Google OpenSocial train

Updated: Confirmed reports are in from Silicon Alley Insider and TechCrunch that MySpace will partake of the OpenSocial APIs as it ramps up its developer platform plans. We'll find out more later today how MySpace's plans to create a new markup language are impacted by aligning with OpenSocial.

Now it's official. MySpace and Bebo have joined the OpenSocial camp. 

This will give the OpenSocial movement major validation and addressable market, given that MySpace dwarfs every other social network on the planet. It is noteworthy that Google is guaranteeing MySpace and the Fox Interactive Media network $900 million in payments ads on those properties through 2010.
