My main problem is with the title of the story. Ideas are not cheap. Bad ideas are cheap. Good ideas that are obvious have probably been acted on by thousands already. Therefore only the non-obvious ones are left and you will only be able to find them by exhaustive searching through many bad ideas. Most of the people here are probably more interested in startup ideas and not story ideas. And you can not just rattle off 100 random ideas every day and expect that they will become better over time. In order to train yourself to make better ideas that way, you need to actually make a business out of each idea and see if it worked. And given the huge cost of starting a business, you cannot train yourself to make better business ideas this way.
