Dan Archer has a very nice comic at the Poynter Institute website—a site devoted to journalism, not comics—about the use of comics in journalism. It's an explanatory comic about comics, in the Scott McCloud tradition (complete with bold-face for the important terms), but it adds a new dimension: Click on a panel and you are taken to a new page with source material and background information. That's the sort of thing you can only do on the web, and I can only think of a handful of comics that have used it (Josh Neufeld's AD: New Orleans After the Deluge being a stellar example). It's a natural for online journalism, and with more periodicals shifting to the web and the iPad, it's something I'd like to see more of.
