Out of Egypt:

A history of my favorite punctuation mark

That's the tilde (or squiggle, according to this source, which is so incredibly nerdy it's cool). There's an old Safire article linked somewhere in there too, which is especially fascinating, since it's being quoted on Usenet, back in the days when Usenet was cool.

Speaking of Usenet, here's something I didn't even realized still existed: the rtfm.mit.edu Usenet FAQ archive. Too bad Usenet seems to have died around the year 2000 and hence none of these FAQs have been updated for around 5 years. Ah well, that's the Internet: always moving on.
