Another webcomic that's worth checking out: XKCD. While this humble webcomic will occasionally make jokes based on science or technology, Russell Monroe of XKCD has made a career of it.
There's not really a lot more I can say. It's just about the nerdiest form of entertainment I consume. That's right, it's nerdier than SMBC. Though SMBC has done a guest comic for XKCD, so that's something.
Anyway, the link is available here, or for a little additional fun, here.
