Hi - it's an interesting take directing this at the creators, but shouldn't it be directed at the curators?
From a cursory analysis of Dtube compared to Utopian, I get the impression that the threshold level of 'awesomeness' is A LOT higher on Utopian - whoever curates that really will just reward the best posts, irrespective of whether they're a new user or an experienced user (it seems).
DTube is another matter - there's just too much trivial rambling, let's call it mediocre content rather than low quality, getting upvoted by DTube!
I don't know enough about D Live to comment.
