There are several games consoles out now that use some kind of social networking to share scores, points and collaborate with other games. Personally I’m more of a XBOX kind of guy but I also have a PlayStation mainly because its a Blu-ray player as well as having BBC iPlayer, ITV Player and 4 on Demand so I have a PlayStation Network account.
One of the services Sony offer is the ability to embed your Portable ID into anything you want
You will notice fro the screen shot that when you generate your Portable ID that you get an embed option and we can copy this into SharePoint.
So maybe your a blogging and host your blog on SharePoint 2010. Now you can embed your PlayStation Network Portable ID in to SharePoint 2010
You can see how to do embed into SharePoint here.
