Talking about ratings and rankings and stuff

So a few days ago there have been these intersting discussions that talk about the ludum dare rating system. They had some good ideas and I had also an idea that I think is great!(everybody thinks his idea is good)

My "good" idea :

So I think that instead of only setting one goal to reach at votes to receive(20) it will be good to set something for games to rate. I know this exists but it doesnt affect ranks. I mean that if a developer doesnt play 20 games at the end of the jam he won't get ranked.

* Also * it will be good if the karma effected the way your votes affect the ranking.(sorry if I didnt express this in an understandable english) basically just like this in newgrounds.(the more karma/XP you have the more your votes are going o affect the game rankings) So that good and trusted will affect deeply the ranks.

* Also * give trusted youtubers and streamers(which are not participating) the chance to rate games like jupiter.

Hope it was clear and feel free to suggest anything!
