This is the kind of advice I searched for. I actually feel like a jackass, but I don't have experience which such conflicts and I let things get out of control. I actually was under the impression that I could change things just by pointing out the flaws. I was wrong of course.

Unfortunately I am the type of developer that's interested in multiple topics, ranging from algorithms (parsers, data-mining, inductive reasoning), to usability. And it sucks because I have opinions about everything.

Thanks,
