Yahtzee, possibly the only game reviewer capable of out-talking a five-year-old with a new Poekmon game, recently made clear his feelings about gaming webcomics. To give you the five-cent summary, Yahtzee believes that video game webcomics are the putrid nesting grounds of wannabes and hacks.
What do you think, class?
Personally, while I have no love for the webcomic that served as the primary target for Mr Yahtzee's rant (Ctrl+Alt+Del), I bear little ill will to webcomics in general. There's a popular opinion going around this here Internets stating that only kings and God should be allowed to produce creative work because humanity is generally not very good at anything. I don't think that's the case.
I don't begrudge anyone their right to produce a Mario x Luigi slashfic. I've put up some pretty horrific creations on the Internet (and since locked them in chains and thrown them in the basement), but with practise I started to produce stuff that's only mildly horrifying. I think that's part of the problem, though: the Internet genie can grant instant popularity. Popularity is the natural enemy of criticism. When you start hearing about how great you are, anyone who offers suggestions for improvement can go suck a lemon.
If someone tells you that there is in fact room for improvement in your work, it's easy to feel, as the kids say, butthurt. It's natural to sulk a little when you recieve criticism, but then comes the vital junction. Are you going to throw it off and get back on the horse, or are you going to shoot the messenger in the kneecaps (as illustrated by Yahtzee)?
The trouble arises when Internet arteests act out the latter. It's no sin to start off with some dull piece of work that you plan to polish and refine. For that reason, I don't discourage anyone who wants to start up yet another webcomic about two jerkwads gibbering on a couch with controllers between their paws. If the author is serious, the comic will become something worth reading. If s/he's not, it'll die within a month or two. We all know the cycle: "No update today. Studying for exams. No update today. Too tired. No update ever again, sorry."
The freak random mutations of mediocre content into runaway successes (Btrl+Balt+Belete) is so rare, I'm willing to put up with these full-moon faerie dances if it means someone else makes a genuine heart-felt climb from Boring to Fantastic.
