By all means I feel we should support developers who put in time to work on an app and put it out for free. But just like paid software I will support with my $ any project that I think is well done. The motivation for many developers is passion, How can I make this really cool, How can I push it. At least make it standard so it fit in and integrate well with the platform. I always use Thomas Perl of the Gpodder fame as a classic example of a developer who gets it right. He and many others like him would get my $ any day
