Go and visit the Outpost (the Op-Ed column at Broken Voice Comics) where today's column looks at why we need iconic figures like super heroes. Go on, it's quite safe. I haven't added a Jim Steinman backing track, or anything!
Disclaimer: I don't have the answers.
But I'll offer some of my experiences and hopefully that will help other web cartoonists find their own paths. I've been at the webcomics 'thing' for about 5 years, and I'm not sure if I can categorize it as a success or a continued experiment with no actual intended result in mind...other than getting my work out there into a larger audience, and forcing myself into a regular production schedule. In those terms, it's probably a success.
I think that the webcomics 'model' has serious flaws. A big chunk of web cartoonists are still trying to appease the comic shop crowds, the so-called 'pamphlet' collectors (I hate the term 'pamphlet comics' as it seems to demean the format into insignificance).
Chad Diez did some great cover art work for the latest Gigcast. We've got Webcomic News, Talking Balls with Wiz Rollins of There’s Always Porn and Yirmumah, and the Music of The Beatnik Turtles.
