Yeah clearly (and by the rest if my post above, i mean CLEARLY
) I meant his was more eloquent than mine. My bad.
Ha! No worries!
You know what's really frustrating? Clearly, Geoff Johns started reading comic books within no more than two years, either way, than the rest of us late-70s starters. So he KNOWS first-hand that there are other ways to do this that are extremely viable.
For example, I think it would be safe to say that "All-New, All-Different" X-Men is CLEARLY the most successful type of thing that we're talking about that DC could do.
Not only did Marvel find the right mix of marrying an old concept and a few older characters with a few new or underused characters, they actually developed those new/underused characters to the degree that one of them, Wolverine, is arguably, and quite possibly easily, the single-most popular character created since 1970.
Marvel had the same problem as DC: The vast majority of their created characters were white males, with the majority of those coming in the 1960s. So what do you do?
You don't create "Roberto Drako," the Latin American Iceman.
You don't create "Warriki Worthigaki," the Asian Angel.
You create Ororo Munroe and Piotr Rasputin and Kurt Wagner. Then, you create Roberto Da Costa and Xian Coy Manh and Danielle Moonstar.
You create sustainable characters who grow into their own niches, who develop their own fanbases. Characters who some will see as reflections of themselves and allow you to meet the goal of diversity while also creating new means of character interaction and growth.
Like Chap said, this isn't rocket science. It's not even that difficult.
It just requires a company to not be lazy, not be cynical, and not always assume that its the old readers who are always the problem.
Old readers don't only want characters they know. Old readers want new characters, too -- very much so.
What old readers don't want is new characters who are really old characters, but only with a different color palette or gender swap.
