I have a personal interest in toasters, I would like to know which toasters in particular you can play doom with? ps. I'm serious. pps. I might be getting the wrong end of the stick.

I would guess that giving your time to a prestigous project that's used by millions (e.g. Firefox) is much more satisfying than working for free on some application used by a small number of people in back offices (e.g. ?). So you'd expect a lot more people to be motivated to work on wide use things like Firefox.

Education has it's own motivations - everyone wants to help da kids right?
