I wrote for them 2 or 3 years ago. They changed their expectations and payment mid-way through and made me very upset. A lot of writers were upset and left when I did. Honestly, I've not heart much good stuff but I think it would have a lot to do with the topic you're covering and how good you do SEO.
Maybe you'll have a better experience but just proceed with caution and don't spend a ton of writing time there until you're sure it's a good gig. Spending more time on HubPages might be a better use of your time in the long run...but that is just my personal experience. Good luck! :)
