Some similar sites are Helium, Triond, Hubpages, Squidoo, and Bukisa. I recommend doing some research on each site before diving in, as they all have their pros and cons. Personally, I'm against most revenue-sharing sites like these. I was lured into writing for one of them for a while, and it wasn't until later when I discovered Constant Content and then the rest of the writing world that I realized how much more money I could have made with the same articles on other sites. Live and learn, I guess.
