I would still pursue your idea and target a younger audience since you are focusing on crushes and not dealing with internet addresses. I would contact people on youtube who have demographics in a younger age range who don't have social skills yet 13-20 and ask them to help promote your site and try using it. They will think it is funny and will help you out. You might contact the Hank and John Green and explain that you are trying to help young people find love.... Also, you don't have to worry if someone got their product out before you. The initial media coverage will not make the product. Also share your idea with school and parent groups.. they will like your idea (I am a parent) Also, contact teen magazines etc. The would find your application interesting and applicable cause teen girls are always having crushes on guys... Hope that helps a bit.
