TheatreFace is a new social networking site for theatre people. It was set up by the publishers of Stage Directions Magazine, so it’s got some oomph behind it. I joined a few months ago and it’s been growing at a phenomenal rate.
Like Facebook, you can add photos and share links and blogs. You can also talk in forums and join groups based on your interests. It has some more theatre-specific features too, such as tracking conversations on Twitter dealing with theatre. Recently, they announced that they will be producing some exclusive content for members, starting with a backstage look at Oregon Shakespeare Festival.
