If you’re the sort that cares about federation, the MediaGoblin project is for you!
MediaGoblin is a media hosting platform, where you can post all sorts of things, like video, images or even 3d models. It’s a nice replacement for things like Flickr, and YouTube, and super easy to set up.
If I wasn’t such a lazy person, I’d have uploaded it to Debian, but alas. Soon. Soon!
It’s an official GNU project, and it’s maintainer, Chris is a totally awesome guy, and MediaGoblin is really important work.
The GNU MediaGoblin is quite enticing. I’m signed up at one of the only public all-access live sites simply known as Gobblin. I have to say, it’s boring as all fuck. I really hope they add lots more features (which they’re planning on doing, so really I’m more or less hoping they add them soon.) and I hope to see it gain some popularity. Hopefully that little GNU in the name draws people in, because that’s the reason I even bothered looking in it’s general direction.
