Nice Post. I used to read the proverbs daily just like you`re doing. Man I gotta get back into it.
I`d say, it means don`t answer a fool.
So, if you ask a question on the board and you *think* someone is a fool, don`t answer them. Truthfully the fruit is on the tree. If they`ve built a business then you can trust their advice. If they`re just giving you free advice then it`s probably worth about what you paid for it ;)
