Yes I am sorry I just put this up and used an existing domain I had I will clean that up soon. Basically it is like a cross between google groups and a blog. So you can share things and cross post to specific groups. Rather than a blog where only one person makes things public lots of people can blog/post/share things publicly and privately. Also you can share lots of things links videos files posts etc and it can interpret them and render correctly. As I said it is like a group blog.
