Two things swing it for me personally. Firstly I love the community and friends I have on Hub Pages - better than any other site. I also love the free platform for writing. There are rules of course, but I don't think they restrict writers and it gives the site a more honest and respected feel. In addition to all that, when you are knew, the site is very easy to get around and doesn't take long - few mintues at most - before you are actually up and writing your first hub.
