I knew 927 was gonna be the top one. It's so useful I sometimes refer to it verbally at work during meetings to great effect.

For me the top 5 will be 927 (Standards), 378 (Emacs), 342 (Internet), 303 (Compiling) and Crypto (386), but not in the order of significance.

Yeah, it's kind of funny that "xkcd 927" is almost a verb now.

It's not a verb, it's a standard ;)

Implied. Eg. A new standard for MarkDown!? Will it meet standard of XKCD 927
