While this is by far our favorite geek vanity plate, we don't pretend that others don't exist. And frankly, if I pulled up behind someone repping a wireless radio standard for all to see on the back of their Hyundai, I think there's a great chance I might spit-take my Big Gulp and risk a rear impact collison. And that's not the only one-Pingdom's blog has a great roundup of geek flags flying high and hard on back bumpers around the world.

Yes, we've got repping of yet another networking standard, one for the Windows keyboard-shortcut devotees, and of course, the social-powered, traffic firehose cycle. Hit Pingdom for many, many more. [Pingdom - Thanks, Peter!]
