I'm a webcomics reader. Well, worse than that really - I'm a webcomics addict. I probably pour twenty minutes a day into checking up on the latest editions of all my comics. When you think that most of those are just three panels long, that's a hell of a lot of webcomics.
When it comes to mass media, webcomics are ranked somewhere between sex tips and Big Brother. Their closest relative, the print daily comic, does a little better, since it has the credibility of it's patron newspaper behind it (Steve Bell's "If" and G.B Trudeau's "Doonsbury" both make credible claims to being adult satires of politics and the life of the West). But webcomics exist in the unfettered hinterland of the internet. Anyone who has been rickrolled, goatsed, or tub-girled knows exactly what sort of thing goes on in the internet (screaming zombie faces at the end of every video, porn sites consisting entirely of hyperlinks to other porn sites, teenagers arguing in mindless sub-English babble over whether "Black Obamma or jon MACcain is gonoig to wiN!!!")
All of which misses some of the most exciting things about the interweb. When it comes to artists maintaining ownership of their own work, controlling the means of distribution, and having unfettered editorial control of their own media, no other channel can make these practises thinkable, let alone practicable. Webcomics are at the forefront of that - some of the most prominent webcomics were established a decade ago and have grown from cottage industry to office business. They survived the dot-com boom and bust and they command advertising revenues in the tens of thousands. Others are amongst the most idiosyncratic and original works of art that have managed to remain accessible and incredibly entertaining.
Which is why I'm going to be giving a run-down of the biggest, the best, and the weirdest webcomics I've ever come across. Hopefully you'll find it enlightening - better yet, hopefully I'll point out a little gem that you've spo far missed.
