The whole thing called "economy" is based upon having an idea. No one will tell.
Some will copy. Some will give advices.
Nothing serious will start that openly.. I'm sorry.
Years, years, years ago. A friend started an "what do you want" website. A simple posting what you want, and a possibility to get reply openly.
It was dead, before he finished the project.
No visitors, no "wantings", no life.. such a good and simple idea, but it doesn't give anything back and solves a problem which isn't a problem
ah, this hurts! But I can see the problem. I knew the risk but still had to at least try making it. Maybe not something serious but one can share little, not so impossible small scale ideas
What happens after I sign up? Are there alreay ideas to vote on? If so, show the number of available ideas.
Even better would be to just show the list and when someone wants to upvote an idea, an account is required.
