The idea of full-time Hive is definitely very appealing, but the caveat that comes up for me is how many "copycat venues" will spring up and make such a thing increasingly difficult, if any significant number of people start deriving the majority of their income from Hive.
Invariably, when "something good" springs up, a bajillion people want to "pile on," and I would be interesting to see if that "full time" thing will turn into the need to feverishly create content on 10-12 different platforms, in order to keep up with every greater numbers competing for the rewards pool(s).
