Bear in mind that "Girl Genius" started out as print, made the successful shift to Web, and has since made another successful shift *back* to print. There was much discussion of this amongst the other Web cartoonists the last couple of Comic-Cons. :-)
Addendum: be sure to check out Foglio's other comic, "Buck Godot: Zap Gun for Hire." That, too, started as print and shifted to Web. Not Steampunk, though, but humorous SF.
