The major difference with software is that you as a developer can immensely help! When a bridge falls into disrepair, you can't just start pouring concrete yourself. But when you encounter a bug in open source, not only can you make a huge difference just by filing a detailed bug report, but you can even fix it yourself and possibly for everyone else.
Seriously, read the OP, it's well worth your time and makes an extremely solid case. It's both well-researched and well-written.
If we stop perpetuating the idea that it's something different than regular software that anyone can modify, then maybe we can get more contributions.
Well, I don't see any roads or bridges...
Also slightly off topic but that is one beautiful document from a layout/typography point of view.
