XKCD - Webcomic

A few months ago I found a really interesting web-comic called xkcd which I've pretty much been keeping track of every since. On Every Monday, Wednesday, and Friday at midnight a new comic is posted. In their own words its "A webcomic of romance, sarcasm, math, and language". Upon further research I've found out that it's never been quite revealed where the name xkcd came from, it's not an acronym though. According to the author it was a random screen name he used that couldn't be phonetically pronounced. I find the comic overall cleverly humorous, clean, and simple. One of my favorite comics I've seen so far is this one about a hamster ball.
