I love the fact that it's open source, with a much faster release cycle than most commercial solutions, meaning it is constantly being improved. I like the fact that, again, with it being completely out in the open, I can even get hold of some of the new features
before they're "released" (I was using the new library for quite some time before 1.8). I like the fact that they (ie. you) listen to "customer" feedback, and again have a very public bug tracking / wishlist system that gets closely monitored, aswell as a strong forum presence from most of the devs. I like the fact that it runs on Linux so that I can run it on a very stripped down, optimised system (not that I am at the minute... but the option's there

). And finally I love the fact that even as a non-coder, I feel like I can give something back - time spent helping (or sometimes "helping"

) people on these forums, bug reports, testing, donations, etc. If someday I find the time I will roll my sleeves up and learn some proper code so that I could have a look at the ever-growing list of bugs/wishes tagged "easy weekend", but that's a while away yet.
That's...about the gist of it!
