Starting a website can be a great way to build some side income in a fairly passive manner. Start a blog if you have interesting, unique, and informative stuff to tell your readers. You can then make money on advertising or having people pay for educational products or tools you produce. Or create a website that brings together buyers and sellers of a niche product from which you can charge a subscription or transaction fee. The key is to think outside the box and come up with an idea that can provide a unique solution for people. And even if you want to produce a website that is similar to ones already out there, do it bigger and better and find a way to differentiate yourself!

Mechanical Turk operates much like TaskRabbit and GigWalk: it’s a corner online where Amazon gathers tasks to be done, people willing to do them, and people willing to pay for them. On Mechanical Turk, you get to do the oddest jobs you can imagine as an online business idea, made possible by a parallel online universe that runs on hits, visits, surveys, reviews, pins, likes, CPCs, reads, and other metrics. But don’t get too ambitious. The small sums being paid out to human Mechanical Turk users rarely add up to anything seriously substantial, even if you invest most of your spare time into it. It's a better opportunity for internationally-based people with internet access and lower costs of living than in the US. Here’s one person’s account of his former life as a Mechanical Turk talking through how he got started with  this business idea and what the experience was really like.
