Sometimes we need a lot of feedback. Specially when we start to make something. But if you try to use social networks or YouTube or anything else you will notice that no one care about things you do. At least when you start something. What if create global feedback service where you can showcase art, music, stories, games. Main goal of this service is if you want to showcase something you should review something. It can be organised as money system, but called feedback points.
It mean if you give a lot of feedback you can wait a lot of feedback at your products.
