Earning money by writing online can be done. We all have read and seen people do it. However this late in the game it is much harder. Main reason is so many people and websites are doing it and there is also such much coping and infringement that it is making it very difficult.
This is more of a hobby of mine and so earning anything is just a bonus. However if I was to pick a site that takes care of its writers, has decent sharing of the profit, and is easy to learn and use than I would have to go with Hubpages. Hubpages has been around for a while now and is ranked at 535 in the world according to Alexa. They are always finding different ways to make the site better, more Google optimized, and over all SEO friendly. Lastly although I have written on multiple sites and learned a lot over the years I find I still have much to learn but I would definitely recommend Hubpages over Infobarrel, or Squidoo, any day.
