This is one of the reasons why I like HN, because nothing in my lower-to-middle-class upbringing prepared me for the notion of stock as anything other than shares of IBM which you held at the brokerage until you needed to retire. Pretty much everything I learned about the mechanics of tech investing I learned as a direct consequence of this site, in many cases to material effect.
One would hope that investors, on dealing with unsophisticated entrepreneurs, would tell them "Hey, it seems like you don't know the ropes of this yet, let me explain it to you" but the overwhelming number of anecdotes where I hear that have that sentence followed by advice so bad it shocks the conscience.
