SlashWeb just posted their list of the 25 Best Programmer Comics. I wonder ... seems like it could have been inspired by the stackoverflow question What’s your favorite "programmer" cartoon?.
xkcd's Proper User Policy apparently means Simon Says (sudo make me a sandwich) comes #1 in the SlashWeb list, versus the stackoverflow community voting xkcd's Little Bobby Tables to #1.
Conclusion? Either way, xkcd rocks.
But how's this for cool: xkcd's "antigravity with python" actually made it in as a patch to the python source code!
