I agree with you, it is quite annoying. I found an interesting quote from a PG's essay "Great Hackers" [1]: "Several friends mentioned hackers' ability to concentrate-- their ability, as one put it, to "tune out everything outside their own heads.'' I've certainly noticed this. And I've heard several hackers say that after drinking even half a beer they can't program at all. So maybe hacking does require some special ability to focus. Perhaps great hackers can load a large amount of context into their head, so that when they look at a line of code, they see not just that line but the whole program around it. John McPhee wrote that Bill Bradley's success as a basketball player was due partly to his extraordinary peripheral vision. "Perfect'' eyesight means about 47 degrees of vertical peripheral vision. Bill Bradley had 70; he could see the basket when he was looking at the floor. Maybe great hackers have some similar inborn ability. (I cheat by using a very dense language, which shrinks the court.)" [1] [http://www.paulgraham.com/gh.html http://www.paulgraham.com/gh.html]
