This is tangential to the content of the article, but ... I'm continually astonished by the number of speakers who seem to be comfortable (largely at conferences) running over time cutting into their question time, the time of the next speaker, or even worse, lunch! Presumably it's not just me and Rota who feel this way, but it seems like there must be a large contingent of people who are very easygoing about it and quite happy to overrun or listen to overrunning speakers. I would be interested to know the thoughts of other HN readers.
