I see how new users with fantastic and quality work are not rewarded.
I hear many say this but I don't see much of it. I believe you, though and would gladly figure out a way to give people a chance to nominate great posts more freely while having myself and our curators make sure there's nothing fishy behind the content cause as you know giving people a way to promote their posts the worst kinds will most of the times be the first to try and take advantage of it.
About communities, we're going to become a lot more strict with the incubation program depending on if the communities and their leaders and moderators are doing good work on curating, maintaining and trying to grow them with our voting assistance. If not we will give others that are similar a chance instead or just focus elsewhere, there's plenty of niche's and community ideas but unfortunately not all that many users right now to truly give these communities a chance at blossoming.
