Nothing is Forgotten, a lovely little wordless comic about loss, fear, kindness, and memory.
Comical is a program that lets you know when a webcomic you read has been updated and allows you to download the newest strip. It's great for people who (like me) follow a ton of different webcomics. It currently supports Over five-hundred different web comics. It even supports Newspaper Comics, Alt-Text, and Hidden Panels. If Comical is missing a comic you like, the program comes with the ability to add new comics manually or feel free to post a request for someone else to do it for you on the forums! [more inside]
The Invisible Life of Poet is a webcomic by Christopher Stetson Wilson that's been published weekly for three and a half years. It features the adventures of nerdy high school student Poet and his retinue (mostly his friend Ben). There are many ways to navigate the archive. For a quality skim, check out the author's favorites. If you want a more indepth look you can check out the tag categories, characters (e.g. Seph the Corruptor, Coach Fathead), contemporary issues (e.g. class warfare, gender issues), culture and society (e.g. mass media, religion), hyperreality (e.g. board games, hallucinations), miscellaneous (e.g. great art, lowbrow humor) and psycho-social constructs (e.g. bullying, love and seduction).
Sad Sack George Baker's subtly subversive WWII strip.

Make mine Maakies Tony Millionaire (who also does related comic Sock Monkey) has all of his sea-faring katzenjammers online. No direct links (curse you, frames!) but you can browse from here. The later ones are better (especially in the 540 range), but all are fun.
When I was in college in the early 90s (B.W. -- before web), I used to subscribe to the daily newspaper just to get my comics fix every morning (back when Bill Waterson, Gary Larson, and Berkeley Breathed were king). Then the web came along and I had to suffer through the only (unfunny) cartoonist to embrace the web. But not anymore. With stuff like Comics-via-RSS and Comictastic I can fire up an app and start laughing every morning. I doubt I ever buy a newspaper again for the funny pages, and on top of that, these even let me avoid the lame ones I don't care about.
