While I don't think it should be done all the time, I really do see the argument for frequent #1s. Say I'm Joe Normal, never read a comic, but want to get started. I go to pick up a Superman comic. What's more appealing? Superman #632 or Superman #1? Seeing the #1 tells me that this is a good place to jump in. Seeing some triple digit number makes me think I would be coming in the middle of a story, and I would be less likely to bother. I think that perhaps renumbering when there's a change in creative teams is a good idea that could help grow the number of comic readers out there. Picking up a comic seems like a less daunting task.
