So, then, Slashdot. That gets you something like 50,000 hits in ten hours, and contrary to naive expectations, some of the visitors wrote interesting comments. This also confirmed something I've long believed, which is that the `Slashdot effect' is something which mainly affects people who've misconfigured their webservers:
-- from the theory, the hit rate should rise instantly from its background value to its maximum value at the time the link was made. In fact it rose in two jumps, because we'd forgotten to remove the compile-time limit on the number of processes with which apache can serve clients. Oops. Once that was fixed, the problem went away.... (Five hits per second isn't very much, of course -- sustained, it's about four hundred thousand visits/day -- but that plot doesn't include the requests for all the graphs in the two discussion pieces to which Slashdot linked; including those pushes the rate up to about 35 hits/second.)
Slashdot didn't link to the quiz itself from the front page, which is slightly disappointing given that the linked discussion articles give away many of the answers. That said, judging by the Slashdot comments, I don't think this will have had much effect on the results....
One other oddity: numerous people complained that, in relation to the question about the first year in which a woman flew in space, the term astronaut is specific to American spacefarers and that the first woman in space, Valentina Tereshkova, was a cosmonaut. This is a perfectly legitimate point; such framing problems will affect the answers given.
On a slightly different topic, here are the quotations and aphorisms which the Slashdot hordes liked most and least from Am I Sig or Not?, based on the change in score from before they arrived to after:
