Why is it web-comics rather than web-fiction?
Is that what fanfiction is? The text-only equivalent of webcomics?
People like funny stuff. Is funny easier to do with a visual medium?
People like pretty things. But one of the most popular webcomics out there is xkcd, and Penny Arcade was popular even before it looked awesome. (Of course, back then, Penny Arcade had a lot less competition.)
Is pure text fiction significantly harder to serialize than a comic strip? The only serialized fiction I know of is Othar Tryggvassen's Twitter. (By which I am fascinated, as previously discussed.) There has to be something else like that out there.
Does anyone blog fiction? There's Banter Latte and Short Little Stories, (both, oddly, by comics bloggers, at Websnark and Damn Good Comics, respectively) but that's not quite what I mean.
Webcomics, at least the serious/story variety, tell a continuing story over a series of installments. Does anyone use blogs to do a similar thing?
Does anyone read them?
(I would mention Doctor Cataclysm, but that's clearly not fiction.)
