3- Curators are not omnipotent or omnipresent

The vast majority of 'curators' read nothing. They have their favourites set to auto-vote and then just randomly pick posts to give their upvotes to depending on what time of day they are online and what's just been posted at the time.
The whole issue of curation is a nonsense as barely anyone reads anything here. It's all about making money. The quantity of a post means very little.
