Making money online is a very involved process and lots of work! Anybody who tells you it's a quick way to riches is giving you bum scoop.
One way to make money online that I've been using is to find one or more companies that I like and promoting it online. This takes quite a bit of effort tho in social networking, building websites or blogs to promote your biz, etc.
I only promote companies where I want to use the products myself so I'd be in them regardless of whether or not I'm selling any product.
