I contribute to open source a lot, but mostly to my own code bases. I seldom fix other open source projects, because they are not well documented, digging other people's code is a pain. Or some code bases are well documented, and their code is also structured nicely, but they have a quite complex or bureaucratic procedure to do code review and submission. I tend to give up in this case and simply file a bug and point out the problem to them. I think I should contribute to open source, because I benefit from them a lot. Every single project I worked on uses open source libraries, frameworks. I should pay my open source tax to support them.
