Hey, been reading a long time, just joined the forums.
I've noticed recently, and maybe this is a feature, but the Next > button doesn't seem to work the way I thought it would. Basically, I was on vacation and missed a few, so i opened up xkcd.com and pressed < Prev 3 times to go back 3 comics. As I read and pressed Next >, I noticed that pressing the next button can not get you to the latest comic. So after reading 2 comics, pressing Next > no longer worked, and instead of directing to xkcd.com it tried to go to xkcd.com/703/#. The only way to get to 704 was to reload xkcd.com or press the >| button.
