I follow a collection of about 40 webcomics each week; one of my favorites is Erfworld, a story about a gamer who gets summoned into a universe that operates under the rules of a fantasy war game. Because of his outsider's perspective, he's able to find loopholes in the rules and exploit them, which makes him highly sought after by everyone who wants to take over the world. It's a great story, consistently funny, and with lots of geek and pop-culture references that emerge as the protagonist discovers the ways in which this strange world parodies and mirrors our own.
But for all the excellence found in the comic itself, Erfworld uses a drop-in solution for their store, which is not serving them as well as it might. As an exercise, I evaluated the Erfworld store as it stands currently, mocked up a possible new design in Photoshop, and sent it to the site owner for consideration in their forthcoming redesign.
