Lightning Made of Owls: a webcomic consisting entirely of user-submitted Guest Strips, launched on 15 November 2008. Its name is a deliberate Word Salad Title. It features the following stock characters:
Holly, an optimistic, lively young woman. Always depicted with clear round Nerd Glasses.
Ambrose, a learned, eccentric older man. Always depicted with a yardbrush moustache.
Samantha, a smart, vain, self-motivated young lady. Always depicted with large earrings.
Comments on a Postcard: Having finally completed their magnum opus, the phenomenally acclaimed genre-defying webcomic known as Postcard, the Comic Irregulars have started to re-run it from beginning to end. But there's a problem - all of the comic image files have mysteriously been deleted! Furthermore, nobody else seems to have ever heard of Postcard, or have any memory of ever reading it. But, unperturbed by this apparent glitch in the time stream, the Comic Irregulars are simply running the News Posts without the comic images, and hoping that the reader's imagination will suffice until they can find someone, somewhere, who has a backup copy of the files in their browser cache. note Actually, there never was a webcomic - the "commentary" is user-submitted and the reader is left to imagine the described non-existent image. Whether or not this even counts as a "webcomic" is a question that'd have Scott McCloud lying awake at night. Launched on 8 December 2008.
The above description is one of many random descriptions of the webcomic that load when the "About" page is viewed.
Awkward Fumbles: Launched on April 14, 2009. A collaborative webcomic where mezzacotta readers send in comic strips with blank speech balloons, and the Comic Irregulars other readers insert dialogue and captions of their own making, to create a finished comic that isn't quite what either of the parties intended! (If this sounds like something that the Dinosaur Comics creator Ryan North already did a while back, that's because it is.)
Continuity Snarl: A natural outcome of having each strip's comments submitted by somebody else. But most of the continuity errors are invisible to the reader thanks to the broken image links, and the rest are presumably due to the frequent Time Travel and Parallel Universe plots.
Lampshade Hanging: One of the "About" pages: "How awesome would it be if someone produced a webcomic without the comic? Each day, they'd just post the author comments for the comic, and leave it up to the reader to imagine what they actually drew. Perhaps there could be a fictional backstory about the mysterious lost comic for which only the author's comments survive."
This was actually the original pitch, as posted on the Mezzacotta forums.
Parody Commercial: Many of the ads appearing in the header are jokes and do not link anywhere.
Public Domain Stories: Each strip includes a copyright line along with its date in the archive. If these dates are taken seriously, then all but the tiniest, most recent fraction of the archive has expired copyrights, or rather, predate the concept of copyright. Given the lack of reasonable copyright date markings, the legal weight of the CC-BY-NC-SA restrictions is nearly as ambiguous as copyright itself.
Ruined Forever: The first line in the first comic is "I think this comic is going downhill." If so, it's been doing so since before the universe existed, so it must either be pretty horrible now or have been really good at some point before.

Time Abyss: Did we mention "making comics since before the universe began"? Even if the Comic Irregulars are time travellers, there are literally quadrillions of comics, sloppily drawn and written though they may be. To create them all manually would require an absurd amount of time.
