Webcomics are comics published on the web. They span all the way from xkcd to HERO: A story - the former a science-centric gag-comic with stick figures, the latter a beautifully painted storybased comic that, for the majority of its chapters, tells its story with the text appearing only as you hover with your mouse pointer over the right panel - and everything that falls between, around and outside that.
I read both of those, and a bunch of others besides. I read gag-comics, I read storybased comics, I read comics about hockey - told in a faux-videoblog-and-social-media-updates style - even though I have no real interest in hockey. I read A Softer World, which is a strip illustrated by photographs and told in a weird mix of poetry and prose.
Some of the most successful comics online are strip-comics. I mean, look at Penny Arcade! There's absolutely no reason why a Sunday-strip shouldn't fit in here.
