While doing research for the new SYAC, I actually stumbled upon something truthful on TVtropes.org. Usually I take everything from that site with a grain of salt, but this one bit actually was surprisingly honest and truthful about webcomics:
Webcomics work on a very different set of standards than other fiction. Almost all webcomic authors are working pretty much entirely alone as they both draw and script their comics and most do not plan any further along than to the end of their current story sometimes not even that far.
Many of them try to adhere to a schedule they aren't really capable of meeting, resulting in them rushing to meet their deadline and making mistakes that should be avoidable. So many of the good 10% lack qualities standard in traditionally professional works. This can be because of the lack of editorial input as well as the lack of lead time. Not all webcomics suffer from this, though, and even the ones that do can still be interesting. Arguably, some strips benefit from their rawness.
Being a webcomic artist is surprisingly demanding. We can't get critiques on every new strip we produce, and often mistakes slip under our radars. I'm not a bad artist, but I do make mistakes... Many more than I probably should were I employed in a position which had regular quality checks and hours. I don't have friends or family who can critique them, so the sad truth is that I am completely alone when I make my comics.
Your schedule is one of the most important aspects you must maintain. Fans plan their lives around your comic releases. If you say you're gonna release a comic on Monday and Wednesday, you'd better do your damnedest to release your comics on Monday and Wednesday. BUT... not at the loss of quality of your work. In the early days of SYAC (when I was literally doing them once a day) I cut corners, I used copy/paste, I ignored background details, and I relied on cheap jokes just to get through my absolutely demanding schedule. It was quantity over quality, which in the end hurt me more than I could've ever imagined. It was a lesson I learned too late.
So please take this article to heart and don't bite off more than you can chew. It's tempting if and when your comic starts becoming popular to update more often to appease the demand, but do your best to resist it. Maintain a release schedule that works to your pace. It's better to turn out a quality product once a week, than a shoddy product every day.
