From its official about page:
9rules is a place where members and readers can connect, build relationships, and learn new thing
in other words, 9rules is a collection of blogs (or a Digg-kind of clone, if you want to put it that way).
I know there are so many of them already out there. However, 9rules.com has a good PageRank and Alexa ranking. That must mean something! I haven’t explored much about 9rules.com but it doesn’t hurt to submit your blog to be approved by 9rules.com, right?
