Who's investing?

Ive been a trader on Hotcopper for 8 years now - probably the longest contributor - and I always get some Buffett type saying this whenever I make a comment of this kind about companies.

Mostly I dont give a damn what kind of business companies are in, but when they cant explain to the informed layman what the hell it is they do, it worries me - especially when peculiar movements in the stock occur.
