The thing about Erfworld is that it's been hit with misfortune after misfortune. Rob's stuck through it, but even back when Jamie was the artist pages were pretty infrequent.
After the switch to the new site and Book 2, there was the whole thing with the text updates and the main comic taking a break, then Xin's mother died, and then Xin got sick, and then... (and so on and so forth).
Rob's trying to get as much out as he can, but he's been pretty unlucky as far as "sh*t going down" goes.
VGCats has no excuse.
At least Homestuck doesn't even pretend to have a schedule, and uploads a few pages whenever the author gets around to it. You don't have to check and be disappointed every other weekday.
In other news, the world still turns, and Penny Arcade still updates every ******* MWF.
