If you Google “webcomics” the first result is xkcd. And deservedly so.
Published by Randall Munroe, xkcd describes itself as a “a webcomic of romance, sarcasm, math, and language.” The comic displays and celebrates a distinctly geeky view of the world, and is comfortable tackling subjects like raptor attacks, sex, computer jokes, celebrities and responding to and creating memes. While most of the comic is line drawings of stick figures, sometimes things do get more artistic. For all its fame, some of xkcd's jokes are unapologetically inaccessible.
That is what makes is such a fun read. Geeky, intelligent and funny. Here are a couple of examples to help you get started.
