With Ning now charging to create social networks, there has been a lot of interest in exploring other options.

I have many listed in Not “The Best,” But “A List” Of Social Network Sites.

Another one went public today and it’s called Stribe. TechCrunch wrote about it in this post. It might be slightly more complicated than some of the other web apps on that “The Best…” list, but it’s free and has some unique features. I’m adding it there.
