In the continuing service journalism vein, Jason Kottke offers "rules for using the NYC subway," which include "Get the hell out of my way, I'm coming through," "If you need to move, do so with purpose and well-defined direction," and "Do not stop at the top of the stairs to put your MetroCard back into your purse/wallet. You are between me and my train."
(Jason's originally from the great state of Minnesconsin, or something like that, and has been living in New York for less than a year. Anil's alt tag for the link reads, "Holy cow, we made an asshole New Yorker out of that nice midwestern boy in just six months!")
