咦,要我介绍一下 xkcd 喵?
下面是 xkcd 的自述
Who are you?I'm just this guy, you know? I'm a
CNU graduate with a degree in
physics. Before starting xkcd, I worked on robots at NASA's Langley
Research Center in Virginia. As of June 2007 I live in Massachusetts.
In my spare time I climb things, open strange doors, and go to goth
clubs dressed as a frat guy so I can stand around and look terribly
uncomfortable. At frat parties I do the same thing, but the other way
around.
