I use the term "comic" loosely as indexed is not what you'd typically think of when referring to one. If you can consider xkcd a comic (and I'm sure most people can), however, then I think indexed deserves just as much consideration for its humor; isn't that what makes a comic a comic, after all? Sure, the drawings in other popular comics such as Penny Arcade and Ctrl-Alt-Del allow them to create characters with which the readers can more closely sympathize, but that's their artistic prerogative. I think comics like xkcd, abstruse goose, and indexed convey their messages, however insightful or humorous they may be, equally well without the need for characters that are consistent across comics.
Today's comic hit especially close to home for personal reasons. In fact, its this type of attention to the ordinary and mundane that makes you step back and realize how overcomplicated we make things sometimes.
Sorry if that sounded really artsy.
