I bet there is not an article ever that talks of making money online which does not include eBay. It would certainly be incomplete. EBay may not make money online as fast as you would want it, but it does generate a good income for those who use it. If you are interested in selling stuff online, then you might just want to try it out and see how it works for you.
There are many sites on the internet that allow you to join and sign up as a freelance writer. A lot of people have not yet realised that there is a huge demand for article writers due to the need for web content on their sites. I actually buy content for my sites from article writers and sites such as About.com and many more use freelance writers. The great part in all this is that you don't have to be an expert in the field.
Etsy
If you do create crafts then you might just want to check out Etsy. This is a huge online market place where different people sell their crafts online. Since this site draws upon those that are mainly interested in handmade craft products, a lot of sellers find this site much more profitable than eBay.
Selling eBooks
Do you have a skill that you think can make you money? Say an award winning cooking recipe? Or a certain technique on training dogs? If you are like that, then write yourself an eBook. You don't need to have the skills on how to write an eBook, just get a freelance writer to do that and you will be surprised. There is one gentleman I've heard of, who makes more than $500 a month from selling an eBook on how to grow tomatoes.
