the reason why the comcis are stuck there is because everyday they are exposed to the front page doubling/tripling thier views. once you get on the top5 it's hard to get off because of that chain event.
Perhaps if the top twenty five or so comics were cycled on the front page randomly rather than by rank it'd get exposure to the ones that are really good but just haven't quite cracked the top spots yet~ A sorta "what people are reading right now" rather than "these are the popular ones" type thing.
Ah, this should go in the suggestions bit~ sorry for taking it off topic. ^^;
