See Excel, Google Maps, Chrome, etc. Really anything by Google starts out amazing, and then ends up as either total crap or relegated into a black hole. MSFT has gotten a lot better, relative to before, but is still terrible in absolute numbers. I know why this is, managers gotta manage, mortgages gotta get paid, etc. but the real question is why do companies get into these traps, even though it happens so damn often? The only thing I have is the Gervais Principle, but even that is too simple an explanation.
