if you have experience with promoting websites, you can make a lot of money by running an affiliate software portal. commissions range from 20-75% and there is no other thing to do than cash the money at the end of the month.
I would say the best startups are - in no special order: Buying and selling on ebay or Amazon Blogging Niche marketing Becoming an affiliate for ClickBank products and putting up review sites.
There are a lot of online opportunities. Although several people have written about some good ways to start, there is something that nobody has talked about yet, that is research! Personally I do not advise anyone to start a business in a unknown are for them because most probably it will fail. Choose something that you like and then do a lot of research in forums and blogs about how to monetize your idea. Nowadays you can monetize almost anything, if... you know what you are doing.
The most important is still staying focus on your choosen niche. Newbie always drifting away after seeing so called the making money ideas one after another ... might end up just reading and reading without real "action".

There is no easy way to make money online. If it was everyone would be doing it. Anything you decide to do requires some upfront work and research.
Affiliate marketing or selling your own products and having affiliates to help sell them is definitely the way forward.
