Feeling guilty because you don't have time to read the important books that could make you a smarter business owner? Publisher Franco Arda is turning some of those books -- starting with "The Long Tail" -- into comics that take less than an hour to read. Arda insists he's not dumbing down the material, however. "These comics can make you smarter. If the text supports illustration, your brain can absorb so much more information," he says.
