Open source is about sharing. If I make something, it works for me and hey maybe someone else might like it too. And if you do like it and want to improve it (say a bug fix or a new feature) please share that back to me.
This is what makes open source work. And most people who use any open source products don't have anything to share back and that is not a problem, hopefully they report bugs and can test things but if not it's ok.
