Earlier quoted context omitted.
If no one will pay for the solution, the problem might not be that important.
100% Meaning that if you solve valuable problems you will [probably] make money. So spend all your time solving valuable problems not posting about $$
But posting about all the money you are making is just silly unless you want a pat on the back. If you really are making bank and you want to get someone to buy you out, then start talking directly to the big players in your market. Then again, you won't have to, because they won't want to talk to you until you are a real threat to their business, at which point they'll be coming to you. Bragging to your early adopter community about your success just keeps them hyped for a bit.
