"They just want to be in control of their data" sure .. but that's not a problem massive centralised services can solve. If you put your data on someone else's computer then who REALLY has control of it? whom you trust is of course your choice and theres no "one size fits all" re any of it. re: opensocial That wasn't about federation. the scope of it was closer to webapps. remember Google Gadgets? it was pretty much based on and extending that. btw I think from memory Myspace was part of that group and implemented some parts of the opensocial spec. I don't remember Facebook being involved with Opensocial.
