I'm constantly confused by this reaction. Why do random arbitrary people think they know what they're talking about? What pedigree justifies such a belief in one's thought process to decide that they know better than other people. That their ideas are better than others. That their ideas are even worth consideration?
I make UI professionally. I've been doing it for a few years, specifically for games. I design, art, and implement. I have experience with standard design principals, common user interaction, and I've been programming for years. Forgive me for believing that I might have some idea what I'm doing.
