I use side projects for R&D and fun. All I invest is time and domain names and effort. I also like them as ways to collaborate with friends and strangers. Right now I'm working on a CI tool, a browser testing tool, a web app for collaborating on song chord sheets, and a new kind of real time database. The chord app is for my band, and some friends are helping. It might become useful for other people. The CI and test tools are infrastructure that I'll use for other projects. The database is a stepping stone for a long term project...
