Social network for sharing sketches and such

so I’ve been considering hosting a diaspora* server for artists and designers to be able to create profiles and share not only pictures and videos but also sketches that may be interactive. I wonder if there is already such a thing so I can contribute to it? If not, I’d like to discuss the needs and wishes of the community for that project to be actually useful.

We have the gallery here:
