I believe that correcting people in public is rarely effective. In this situation, if I knew a "better" way to do it, correcting the speaker & hijacking the preso is not likely to produce positive results. First, people will focus more on me hijacking the preso than whatever it is I'm trying to say. Second, even if I successfully communicate my "better" idea and save a room full of programmers from a bad habit, I'm not giving them the judgement necessary to avoid the next programming mistake they'll make. Lastly, I have no interest in being right if it means drawing the wrong kind of attention to myself on Hacker News. It does make a good story though, and it's pretty good PR if you're trying to be infamous :)
