Through happenstance (a) a conversation distinguishing between these came up at Doyce and Kate’s Saturday night, and (b) I found a forgotten blog post linking this while cleaning up during my WP conversion. The original link had rotted, but I was able to find the cartoon again: The Difference between Geeks, Nerds, and Dorks.
I think that makes me a Geek.
On that note…
Nice.
