This is so true it hurts. I worked for years at a certain Silicon Valley BigCorp on a low-level networking library with one other guy. We of course had bugs but we managed them and delivered on time. It was therefore assumed that our library was "easy" (it wasn't) and the buggy deliverables that made up other parts of the application were "hard" (they often weren't). So the folks who eventually delivered the buggy libraries got the recognition while we toiled more or less in obscurity. It was a bitter lesson in the importance of self-promotion.
