My own sites make the most money for me. Probably because I don't place any restrictions on myself as to how many affiliate links I can have, what sites I can link to, where my ads are placed, what topics I can write about, or what kinds of interactive elements I can embed within the pages. Plus I don't have to share my revenue with anyone.
All revenue sharing websites--HubPages, Squidoo, Infobarrel, Bukisa, etc.--have some restrictions that are meant to benefit the site owners, not the writers. And you never know when they might change the terms and conditions.
That's why anyone who wants to make money from writing online should set up their own website(s), either as a main source of income, or at least as a back-up. If you only publish your articles on third-party platforms, you could be in for a unpleasant surprise down the road. And personally, I LOVE building websites; it's another creative outlet.
