Ah yes, I read sinfest also. But not the other two you mentioned.
I'm not going to link all the comics I read... overall there are 61 webcomics I check daily (most only update once a week though. But it's easier to just open them all up at once). I used to write a webcomic myself, but it fell by the wayside. It was mostly comedy, and only had one actual ongoing story (which never actually was publicly aired) about a guy that was hitting on me in a bar (I am so dense sometimes. It wasn't until after he bought me two drinks and paid for 4 or so games of pinball that I realized he was interested in ME, not the pinball game I was playing).
