I would add that acceding to the corrections of another is somewhat of a compliment - particularly to nerds. In fact it is a strong enough status signal that I don't expect high status people to acknowledge such correction unless they cannot get away with not doing so. [emphasis added]

This is one of the things that bothers me most about LessWrong, and intelligent people in general. Of all the silly status games that I would think and hope people here are mature enough to see through and realize the silliness of playing in this environment, avoiding giving thanks and acknowledging errors is one that should be close to the top of the list -- but sadly, it isn't.
