The pluses outweigh any negatives in my opinion and experience in drawing comics for over 13 years now and I've seen it all come and go and come again.
Well as far as the “rights” thing goes and signing things away, you're not really selling it whole hog, you're included in being the creator, and royalties on just about anything. If DC starts selling your comic as a scented fart, you get paid. Plus they pay you 250 a page if you get the contract, that's nothing to sneeze at, AND you'd suddenly find yourself with real inside connections at DC, Time Warner… People ARE going to take you more seriously if you have those affiliations. Hell you might be able to land big gigs outside the industry just by having those things as credits– and it's a hell of a resume thing to have in your belt. I think it's all how you work it as your own business man, if that makes sense?
As far as the “format” of 800x600 goes, if you talk to them, I think they actually MEAN that it has to be that proportional shape of page size. When you hit “full screen” on the flash player, the images are much larger and more detailed. Zuda actually asks for a higher resolution final file— they just mean that proportional landscape size is all. So IF someone with a 800x600 size screen were to hit “full screen” there would be no scrolling.
i think dj has some solid points about the positives that might come of zuda, not just to the creators there, but the webcomics community. maybe with DC getting involved in webcomics, it will become more mainstream, but then again, that gives the risk of it becoming a soulless corporate gimmick and would lose some of the independent beauty that webcomics have. i don't think zuda though, is for a lot of people that are in webcomics right now. it honestly seems like they want professional cartoonists working as if they would for a sindicated strip. the format reminds me a lot of sunday comics in newspapers with those restrictions.
i think right now DC is playing it pretty conservative and safe because they are journeying into a new market which is still very much emerging. i wouldn't let creators go wild and create anything if i was a business and thinking of an investment. i at least applaud DC for trying something new but i fear (and anticipate) that it will not go over well. as many of stated before, these comics do not have the same ‘feel’ as many webcomics do. they seem a bit soulless, and thrown into the submission because creators are scared to give away their baby.
honestly, i don't think its for me, or many webcomic creators here because we didn't go into webcomics to make money or sell the story. we do it because we love the freedom and structureless beauty that webcomics offer us. ultimately i don't think DC will ever truly do ‘webcomics’ because they are a business, looking to make money, not to create art or stories.
