It's the only webcomic that I ever actually followed. It is mostly a lot science, math, and computer programming humor.

Post some of your favorites! This is one of mine.

xkcd: Grownups
That was an easy pick I would love to do that...
Love this comic :D

@Poet: Haha, that one is really cool! It's like of a fantasy of mine as well. xD

A lot of the earliest comics are quite romantic. >3<

Oh oh, here's a another really good one! Especially if you like Magic School Bus.

Haha I grew up on that show

Actually ever since taking engineering classes his jokes have gotten WAY funnier....

Haha, I kind of know what you mean, except for programming and math instead of engineering. I have never taken an engineering class, though I do know a lot of engineers. I go to an engineering school, so every other person I meet is an engineer, haha.

I took programming (didn't do well), engineering (which requires extensive math) so anything related to those make sense.
The only ones that confuse me are the science and the linux ones.

I love xkcd!

xkcd: Pointers
xkcd: Sandwich
xkcd: Grownups
xkcd: Minifigs

I'll stop now. I just have too many favorites!
