I have a great Idea, and it is FREE for the first customer! Here it is:
Create a thread and say you are selling an idea. When someone buys it, tell your customer the same idea you are reading right now.
It's a bit like ponzi: if noone wants to buy The Idea from you, then you lose your money.
The above is similar to a website, which promises you can make lots of money with a method. To get the method, you need to do a survey. If you do the survey, you get a text file telling you to create a website that gives users the exact same text file for a survey.
an old idea !
