Why do you hate xkcd

I would like to know why everyone hates xkcd so much.  The comics are clever, funny, and fresh, the author isn't trying to make a funny comic just to get rich, and the author has alot of neat ideas like mapping every IP address, mapping the internet, and Geohashing, among other stuff.

So those are my reasons why I like xkcd.  I don't see what all the nerd rage is about.  Please reply with good valid points of why you hate xkcd instead of the typical troll fest that /prog/ is.

The whole internet does that now :/
