I know of a few nice ones that have a solid story and artwork and are actually complete:
Freakangels
A story of a group of metahumans in a flooded, post-apocalyptic England, with steampunk elements. Written by Warren Ellis, who's well known in print comics.
A Redtail's Dream
Already mentioned above, but it deserves its own link. A story that takes place in a dream-world inspired by elements of Finnish mythology. The artwork is gorgeous and shifts through a different colour pallet for each new chapter.
The Phoenix Requiem
A fantasy drama with a Victorian England aesthetic and supernatural/horror elements such as spirits and shades.
Problem Sleuth
An earlier comic by the creator of Homestuck that parodies private eye stories in the form of an stick-figure illustrated text adventure. Begins with a locked-room scenario and escalates to over-the-top battles on a cosmic scale.
And also, here's a group on youtube who've done a voice dub of the first 4000 pages of Homestuck (i.e. all of Acts 1-5), for anyone who's interested in the series but has difficulty with the length or slow pace of the earlier acts: CoLabHQ
And a couple of ongoing series:
xkcd
"A webcomic of romance, sarcasm, math and language" There's usually no continuity between comics (there's even a randomizer button on the site), and every comic has a hover-over text segment to watch out for.
A-Minus-Minus, Shoot for the Moon, Birds and Dinosaurs (typical page examples)
Movie Narrative Charts (occasional, more extensive comics)
Time (this one is actually a 3101 frame animation updated over 124 days, so the entire animation is hosted off-site)
Bad Machinery
A collection of stories about two group of school-kids in the UK who compete with each other to solve mysteries (with a bit of a paranormal slant), while meandering through tangents and side-stories.
Darths and Droids
A Starwars comic that uses screencaps to tell the story (starting with Episode I) in the style of a group of players in an ongoing Dungeons & Dragons game. It makes the prequels much more enjoyable to me, anyways.
