Only because I forgot about it. 
Also forgot about The City (one of the best online strips for political, and other, stuff) and City of Zeroes (a peek into the life of City of Heroes’ pedestrians).
Thank you both for these two. I enjoyed them.

oh and thanks from me too. i haven’t posted because i’m busy checking out the links. this will take some time…
Our work here is done… 
Sweet! It’s got the snark of xkcd without the overdoing of the nerd appeal, as well as the often highbrow sense of Partially Clips, and the whimsy of PBF.
+1 for Minus. I love that strip when it updates.
Herdthinners, Questionable Content, Wapsi Square, Ctrl Alt Del, Bunny, Two Lumps on occasion (although I’ve developed a dislike for that ever since I found out that the artist (as opposed to the writer who is his lovely wife) has an irrational hatred of things such as nanowrimo on grounds that they ruin things for Serious Writers, Suh, like him :dubious: ), xkcd, occasional Sinfest.
SPQR Blues. It’s a Roman soap opera. Although I’ve found that I usually have to do some thinking on it to connect one day’s strip to the next – a lot of stuff happens offscreen – I still enjoy the art and the historical research.
oops
Thank you, thank youall! sniff you’re so beautiful I’ll be up all night looking at these links…
I have all 13 issues of GirlGenius the comic, 14 if you count #0. Honestly, I had no idea all this stuff was on the net… I’ll throw this in: Galaxion
Dammit.
Galaxion
Achewood is simply the best webcomic ever. It’s a bit tricky to get into, but here’s a good start:
The Ray Smuckles Decision-Making Flowchart
Ray gets sort of stoned
The brave little Dutch boy / Lie Bot
Roast Beef buries his shirt
Looking for Group if you play World of Warcraft (or even if you don’t–Richard is funny even if you’ve never played a MMORPG).
Two Lumps if you like cats.
Another shout for the good Dr. McNinja. There’s a funny D&D one I found recently. And this one is about tentacle monsters and the girls who love them (note, linked strip is SFW, but click past that and it quickly becomes NSFW).
And another voice wondering wtf happened to Perry Bible Fellowship.
The now defunct Spamusement! did single panel comics inspired by spam subject lines he’d get in his in-box. Best to start from the first one and work your way up.
You may enjoy MC Frontalot’s Achewood-inspired song, Livin’ At The Corner Of Dude & Catastrophe
There’s a teaser MP3 of the CD-version of the song at the bottom of that lyrics page, but if you go to this page and scroll down to where it says “SongFight Contenders”, you’ll find the original demo version of the whole song.

On another webcomic front, does anybody know what the hell is going on with Chugworth Academy? Some time back there was some sort of server problem that caused the strip to disappear from the Internet for 6+ months. When it finally came back online it quickly became apparent that the author hadn’t drawn a single new strip in the entire time the site was down (you know, take the opportunity to build a backlog/buffer). Since it’s been back up, I swear that updates have come at the rate of about one strip per month. I’m bummed, because this was one of my favorite webcomics.
Just a shoutout to User Friendly with Saturday’s Comic. I found it very funny.
I’ve found that this type of drop-off in content is usually because of World of Warcraft, or some other MMORPG. Right now we’re seeing the (hopefully temporary) effects of GTA: IV.
