I very much agree with this. After all, there are a lot of hobbyists here who update every once in a while, but also professionals and wannabe professionals who update weekly, or even several times a week, and work full-time on their series as they try to make a living of it. It's a hard choice of life, especially since getting published is so hard nowadays with the delcine of print industry, and though I don't mean to say that they should have more audience for the sake of it, but it seems fair to show who's active.
In a same direction, but slightly different, maybe it would be nice to see (aside from "recently updated") a list of "active comics" that would be listed by amount of monthly activity (maybe based on 3 months worth of activity). It would be like an averaging of how many episodes were submitted per weeks over the 3 months, to determine number and regularity.
So, if I submit 12 episodes one day, and then nothing for 3 months, I would have a bad score for regularity, putting me toward the bottom of the list. While if I submit 1 page per week, I would have a better score for regularity, putting me toward the top of the list. It can be nice for people who seek ongoing series.
