I am amazed as to how people dare to put up such services which involves their potential to earn huge and at the same time give paid services to others.

Well once you are earning enough money then you don't really go on using it to market yourself but in reality you just keep on improving yourself and then people follow you!

Well Elon does not tell us why to buy his cars or why to invest in his spaceX projects, people simply believe him because of his work!

It's a big example, but peeps; come on grow up and provide some standard services which can actually benefit the community itself.
