This isn't a comic. It's a science classroom poster. Seriously, what's here besides a log scale and a bunch of internet jokes, including, I'll note, a healthy dose of his own (sorry Randall, but xkcd really should not, by any reasonable standard, have at least as many references as futurama and HHGG combined).
I mean, why not just print out the front page of digg and paste the pictures on this:
Anyway, in conclusion, there is nothing in this "comic" that is both new and funny.
update: Well that didn't take long - there is now a poster of this "comic" that you can buy to put on the wall of your freshman college dorm room and hope people of the opposite gender like it! Wow, thanks again randall for helping us out there.
It really bothers me that the poster was clearly all ready to go before the comic came out - making the comic little more than an ad for the newest product in the xkcd store. LAME.
