It's not that it's fragile. The key with this project is to be the first. I've never seen it done before so I want to do it before anyone else does. Sorry for being so vague. Thanks for the input though.
This is usual a sign that someone with more money will reproduce your success once you prove the credibility of the market. If it is that simple to reproduce then you don't have a strong product. If it is a strong product then you can tell the world and it does not matter. Some blasting Facebook and twitter with advertising idea, that anyone can set up with a server and some JavaScript is neither novel or a strong idea for a long term viable business.
If your idea is so fragile that discussing what it is will destroy it, you really don't have anything useful.
