I agree with your son completely. The web fits over the top of the Internet. The Internet is a service upon which the web relies. However, many people very commonly conflate these two very different things. And my question is: how widespread does a mis-usage have to be before one just gives up and says, "Okay. Have it your way!"

Right now I can't stand the terms "DIS" or "disrespect" used as a verb. First, it doesn't sound right and second, there's something about people trying too hard to be cool that I find offensive. But the world is passing me by. The usage is already very widespread. I reckon that in the near future we'll start seeing these in dictionaries and then it won't matter how much it sounds like fingernails on a chalkboard to my ears. (I get the same irritation when I hear people say "taters" or "sgetti.")
