How about building an open source activity stream app ?

Use Twitter Bootstrap for the UI and just have a simple generic REST service you can push activity events to. This would also allow you to get some exposure into WebSockets. Maybe even try and do it in Play, Grails, Vert.x etc for something different.

You could even turn it into a little startup.

This actually sounds pretty interesting and I would really like to fiddle with this idea. The thing is right now it actually feels like biting off a bit more than we can chew. I might just come back to this idea somewhere in the future, since I find it really intriguing.
