I agree. And let me retell the story from a different point of view: Even if you're a humble .Net (I know, I know.. You'll get a lot of interesting looks mentioning OS and .Net) developer by day, you can easily dive into very nice and cool OS projects.
I've (online only) met one of the coolest guys ever due to him maintaining a very nice project that I use a _lot_ and me being able to contribue a teeny tiny bit of code. Hey, although I'm a cross-platform guy (Windows during the day, Linux in the evening) I could help with experiences on both platforms. Don't hide behind "Not on Linux (or *BSD, to stay somewhat on topic), cannot help".
There's a downside though: If you like the contribution, like the people that do the actual work (i.e. the maintainer) than you might end up with a little guilt for not being more active. I know I do...
