I saw that, but I totally don't get it. Since when am I looking for a webcomic about something? Like... "Today I am in the mood for a webcomic about dinosaurs!" Is it just me? I just don't know what I'd ever enter in that search box (as much as I appreciate the concept).

I think this was invented purely for MeFites to derail comment threads with appropriate references from Web comics. I think this is a noble purpose.
