This is just something inspired by a comment in another thread.
I've noticed recently this is one of the many areas that Superman fans often differ in, as some fans think Lois should be a supporting character who should be there when its important to the story, while others think she's a big enough character that she should almost always be included.
Personally I've always thought that she should remain a supporting character in Superman's books, but at the same time I understand that her fans would want to see her featured more. She has in many ways grown past a typical supporting character, and that's one of the reasons I think a solo book would do her and the Superman family some good. It would allow fans of hers to have their Lois itch scratched while keeping pressure of the Superman writers to have her in every story.
Anyway, opinions?
*Edit: Damnit, could one of the mods fix the title for me?
