Time for a new idea?

Idea born during the night: http://discussdebatedecide.com (DDD-democracy reinvented for the 21st century) at the moment this links to this current post, the idea is only a few hours old :-)

Embrace the origins of active debate by citizens, powered by the social media technology of today, so citizens can feel empowered not overwhelmed and believe again that their voice matters, discuss important and interesting ideas, actively debate and then decide what to do next.

What needs to be done to get this concept going? Decide on the optimal number for each DDD, based around Dunbar's number of 150 (or Bernard–Killworth median of 231 or council of 500 from ancient Athens), how to pick the participants for each question, how long each debate should occur (a week, a month, a year), how to promote the idea to create a Facebook level of interest not a Reddit level (in the popular consciousness), how to decide which ideas that spin off to choose for the next question for DDD?

According to statista (https://www.statista.com/statistics/433871/daily-social-media-usage-worldwide/) we spend 135 minutes a day on social media, what if 10% of this time was spent discussing, debating and deciding the most important ideas that affect us all, rather than just posting pictures of your lunch and watching funny cat videos?
