I'm not a typography geek (or even a designer), but I'm fascinated with how passionate people can be about typefaces. The documentary mentioned in the article, Helvetica, blew my mind, mostly because of the passion/conflict/opinion that people have about something I take wholly for granted.

Warning: watching this movie may have self-image ramifications such as "Wow, did I just watch a documentary about a font?" :)
