At one time, I would say to stick to Hubpages. Now I think Google just changes too much and you never know what to expect as far as traffic. I wouldn't drop my Hubpages account. Hold onto it. Just put some effort elsewhere. You never know when Google will change their mind again.
I have a Blogger blog, but to be honest, no one clicks on the ads. The traffic hasn't been bad, but no earnings.
I have 3 websites at Tripod Lycos. I just pay $4.95 a month for all 3. I've had these for over 10 years. At times, I do very well with them. At others, Google hits them too.
I would stay away from Squidoo for now. At one time, you could earn big bucks. Ever since they got hit by Google they are going crazy over there. I had two articles taken off for copyright infringement when I wrote them myself. They are denying lenses right and left from all their writers for all sorts of crazy reasons. Wait until they settle down a bit.
I haven't tried Wordpress, but I know if you don't pay a monthly fee you won't get ads. Many people swear by Wordpress though.
Right now the place to write seems to be Bubblews. You can put in little effort and earn money there. Some writers are doing really well. I'd keep my Hubpage account and do some writing over there for income until Hubpages picks back up.
