I stumbled upon this project today. ClearPoll is a new project (currently in Pre-ICO stage) that aims to provide a social app where users can choose topics and vote on polls, to have their say. It uses blockchain technology to store their votes and the final poll results, so nobody (not Google, not Youtube, not Facebook etc) can manipulate public opinion.
This app will let society see what people really want, not what the (corporate owned) media says we want.
I suggest you check it out, it's a great application of blockchain. These guys deserve some support!
It's not every day we see an ICO for a project that you can actually imagine existing and being useful.
