Xkcd

xkcd is a webcomic created by Randall Munroe. The comic's tagline describes it as "a webcomic of romance, sarcasm, math, and language." It has been recognized in such mainstream media as The Guardian and The New York Times. The first strip was printed on September 30, 2005 and since then has massed over 1,400 strips. It can be found here.

The subject matter of the comic varies, including statements on life and love (some love strips are simply art with poetry), and mathematical or scientific in-jokes. Some strips feature simple humor or pop-culture references. Although it has a cast of stick figures, the comic occasionally features landscapes, intricate mathematical patterns such as fractals (for example, What If shows an Apollonian gasket), or imitations of the style of other cartoonists (as during Parody Week).

The comic is available under the Creative Commons Attribution-NonCommercial 2.5 License. New comics are added three times a week, on Mondays, Wednesdays, and Fridays at midnight North American Eastern Time, although on five occasions so far they have been updated every weekday: Parody Week, the "Choices" series, the "1337" series, the "Secretary" series, and the "The Race" series.

The comic is notable for having many of its jokes being imitated in real-life [citation needed] such as [citation needed] protesters carrying [citation needed] signs the way they did in strip 285 (July, 2007) [citation needed].
