Comic Book Collectors; Nerdy Geeks or Shrewd Investors?

When one says, yeah, I collect comic books, what is the general public response? Oh no, a slightly off the wall geek. Here is someone who has lost touch with reality. Or someone that is in his or her own little world. I think not. Yes, comic book collectors may sometimes march to the beat of a different drummer, but who says we all have to be cut from the same mold. Comic books are big business.
