Has anyone dealt with HubPages?

I’m trying to increase my income and free-lance writing seems to be a good idea. HubPages seems to be one site that isn’ asking for money upfront. However, I wonder has any other Doper used them and how good has the experience been? Are they legitimate and can you earn some cash?
All replies are appreciated.

Perhaps I had better rephrase this? How do you find out if Internet sites for free-lance writing are legitimate?
