I made passagemaster.com, an online app for memorizing anything. It used a review system that focused on not only memorizing things, but not forgetting them. I mostly made it to learn about web development, but half hoped I'd get at least a few users. The only marketing I did was emailing a blog to ask them to add a link, which failed. It's been up for about 6 months now, and I currently have 0 regular users. I only spent about $40 on it, so it wasn't that much of a loss. I ended up using it when job searching, and I now have a full time web development job, so it was definitely worth it.
