I don't quite understand you guys. The question is, "Have you ever come up with an idea only to find someone else profited from it years later?" Let's get in detail here: Come up with an idea to find out someone else profited from it years later This means posting ideas that are already being exploited by somebody else. So what's with this " I WILL NOT POST MY BEST IDEA HERE" attitude? Nobody's asking you for that. My idea: Create a type of plastic that would not leech its chemicals into food when heated or frozen.
