As an editor, I add episode lists, cast and crew, airdates and trivia, quotes etc. to shows that I am the editor of.
Well, that's reassuring. Whenever I hear someone's an "editor" of a past work I think of things being excised, especially in this shameful era of political correctness (Huck Finn, anyone?). What you're doing sounds more like "curator" or "archivist," which is awesome.
Might it be a good time to consider my suggestion to you -- that you open up the blog to all of the classic DC characters. By classic, I mean the long-lived, heavy-hitters like Green Lantern, Wonder Woman, Batman, Flash, Green Arrow, etc. Even the Legion of Super-Heroes and other Superman offshoots like that.
I'd certainly consider the Legion, which I love. Wonder Woman I couldn't care less about, unless her bustier is inhabited by Lynda Carter. The others might be a stretch, if only because I want to eliminate duplication of effort, and Pat Curley's doing a terrific job covering the "Silver Age" in general at his blog.
I guess you could make a case that any title published under the "DC-Superman Comics" bullet is fair game. It's something to consider.
