I would suggest a 0-5 rating scale instead of hearts. It would lead to more compromise in our discussions, better allowing us to reach consensus and improve the quality of our discussions, which is vital for our survival and success as a group in the face of our many challenges. This could be the edge for cardinal supporters to unite and work together to enact superior voting methods. I also think people would be more willing to write comments that incorporate various popular ideas (‘compositing’ as it is known in this book) and thus quicker lead us to right theories and good ideas.
Edit: Just found a way for this community to execute 0-5 ratings at https://meta.discourse.org/t/ratings-instead-of-hearts-for-likes/122813/4
