*cracks knuckles* Okay let me see if I can remember them all...
XKCD
Penny Arcade
VG Cats
Bob and George
Order of the Stick
Dominic Deagon (The author is a swell guy who I had the honor of befriending in person after meeting him)
Pon and Zi if you count it. I recommend this one to all ages and interest groups. Cute, funny, and romantic at times. Little one-panel pics that are hand painted.
Megatokyo a few years back.
Oh, I almost forgot CTRL+ALT+DEL - I even own the animated series that was a brief offer on the 360. Well worth the 30+ dollars
.
And a few adult-oriented ones do to sexual humor / references / swears / offensive jokes.I will not list.
I read Brawl in the Family. I find it to be interesting.
I've been meaning to start one called Snow by Night. I heard about it from the anime convention I went to. I even got a character card from it and it's saved in my favorites. I've just been too busy to start it since it has like 3 chapters out.
