First off, this is a fairly confrontational and antisocial way to make a point about social graces. Also I’m puzzled that someone made an entire website based on one assumption. If someone says hello to me and doesn’t continue immediately, or even if they do… I’ve already switched to another window. The initial “hello” is perfectly fine for getting attention and informing someone that you wish to speak with them in the near future. There’s no reason to assume they are staring at the chat window, immobilized, twiddling their thumbs and waiting for you to continue.
