As a developer and full time ubuntu user, (at work and at home), I feel I have no room to complain about anything. I don't give anything back to the community which works hard to provide, all of us, with free and pretty stable software. I don't submit bugs. I don't support a project and volunteer my own time to help support it. I don't pay a dime for the many applications that ship with ubuntu. Yes, it's frustrating at times when something doesn't work. But the reality is, I can't really complain for something I don't work on, support, or pay for. If we all really want this amazing experiment, of running a free - and - open desktop OS to succeed and flourish. We should probably find more ways to support it. I know I should. Major thanks to all of you who do though!
