What are some social networking websites you know?

[The Unnamable]

I mean some sites other than Facebook, Twitter, etc. Some which are not so well-known, but good ones. It could be about particular subjects.
And please tell me if you are familiar with them, the pros and cons of them.

Thanks in advance.
