Umm what? Whether you agree with my opinion on it being a mess or not, I'm pretty damn justified to have one. We don't have to agree.
Most of the people buying graphics cards have confusion when looking at Nvidia's (and to a lesser degree, AMD's) GPU lineup - there's no clear direction on what product one should be choosing. I absolutely understand you may clearly know and differentiate the purpose of each model Nvidia have released in the 30 series, perhaps in part to having ~17,000 posts on a tech forum/site, or having a keen-enough personal interest.
Still doesn't mean that the stack isn't a mess in my opinion.
