It's been a few months since I posted my current webcomic list; I've added quite a few things as I've settled into using Piperka to track my comics. I think my favorite still has to be Pinch of the Glass—the current storyline is awesome and the art tends toward luminously beautiful…
This list is roughly in the order of most-to-least enjoyable for me, but with the caveats that I get more enjoyment out of frequently-updating strips, and that I haven't put a lot of thought into the ordering, and that your mileage may vary strongly. It is missing a few strips that I either am embarrassed about or am dropping.
[*] Contains occasional "mature" content.
Mostly my list has grown. I'm still open to a couple more strips, but I am getting close to my reading capacity unless I kill one of the dailies like Mansion of E.
I also really haven't killed Arthur, King of Time and Space yet, although if the author is really committed to drawing only in triangles for the foreseeable future I'll probably put it on hiatus. I love the strip premise and always find it a pleasant read, but I'm kind of picky about my comic art. (B)
