I'm lurking on Diaspora for several months already (same username). There are
a lot of interesting news about free software and GNU/Linux.
I didn't find a lot to do there besides reading news, but there seems to be a
picture sharing service that you can use to share photos with friends. Never
used that though.
You can also add friends and PM them of course, or fill out some forms about
yourself. Diaspora is in quite an early stage right now and in need of heavy
funding, I'm afraid they won't make it without a lot of donations or some
different kind of funding.
