Thanks everyone for commenting.
I totally get the point of costumer feedback, but, my goal from sharing my idea with other entrepreneurs is to connect with potential co-founders. One way might be to read their profiles in founderdating website and try to message them one by one. But, I do not see that very efficient. I am thinking of a platform that I can share my idea and other entrepreneurs who might be interested get involved in a discussion and ask their question and I can answer and we see if we can collaborate. I am looking for a online place to network and socialize with other like-minded people. I think this could be a feature in this website itself.
