To me, that sounds a lot like a 2 year old type of behavior. Does anybody really even care what a TLD is or is "meant" to be used as? Honestly, if it's not a .com, most people are going to screw up and add .com out of sheer habit.
It's the friggin' internet. If it's out there, someone will do something they feel like doing with it even if that's not the originally intended concept.
