Depending on what you want to do there are a few different options. The two that come to mind are search engine evaluation and article writing. This has a list of some options that are available, along with lots of discussion about the merits and drawbacks of each. The two I have heard the most about are Demand Studios and BrightHub. The fact that you already write for this site will help you there, since it shows you're already used to dealing with an editorial process, doing research, and writing for an online audience.

There are also inbound call centers that allow you to telecommute like Sutherland. It's often hard to know whether one of these is legitimate, but that one is. Sutherland provides level 1 tech support for many different software companies, and no experience is necessary.

Good luck!

Generally, most are fakes. Real work-at-home jobs are few and far between.

Most of it's fake/fraud unless you want to get into camming (but consider if having that on your tax record will be an issue with future employment).
