For my part, as someone who writes a lot of crossovers, a wiki devoted only to L&C wouldn't be useful - I quite often want to check out the career of the actors, how the character appears in the other DC universe stories, and so forth. I think it would only get a tiny readership compared to the main Wikipedia articles on Lois & Clark, and that the effort would be better used there, improving their accuracy and scope, adding more episode descriptions, and so forth.
