  1. For some reason, I checked just now that the first revision to the nLab was made on the 28th of November 2008. So this date may serve as the 10th birthday of the nLab, if people wish to mark it in some way!

    I am not quite sure when the first edit with significant mathematical content was made. The page classifying topos was one of the earliest created, but there was not any serious content on it for a while.
