Actually, speaking as the biggest nerd around (I was an invited [and paid] guest speaker at the Superman 50th anniversary celebration), the 'S' stands for 'Superman' -- all that other stuff, like it being some family symbol in Kryptonian, got started with that silly movie in '78. On the other hand, he dedicates his life to helping other people without asking any compensation, saving countless lives, frequently at the risk of his own. In my book, that lets you call yourself any damn thing you want to.
