Oh, look! A new post to the thread! Must be somebody posting how he actually prefers something other than the thread topic! How interesting!
I believe the curious case of Socrates can shed light on this phenomenon. Apparently one day he suggested a thread topic (in the Athenian Forum, I guess) and then asked all the wisest men in Athens to post a response using their computers. Turns out that everyone
posted about something other than the thread topic, and that's how he realised he was actually himself the wisest man in Athens because he was the only one who didn't have a computer. Of course he never realised what amazing CD bargains* he was missing, but that's another story.
I may have got the details of this wrong here and there, but I'm pretty sure the gist of it is right.*Of course in those olden days it would have been vinyl LPs.
