I don't know if @steem-ua is all we hope for it yet...but it really is a good choice for ROI for good users.
Me either which is why I think it needs to be tested well. And yes, it is good to actually discoer posts but with limited time and active SP, there is no way the search is posible. Perhaps in time, this can bring more people up to a level where they can search with SP.
Hypothetically, if someone works from 100SP to the 250 SP for 7 votes, every SP past that can go into curation. Currently, there are only a little over 15000 accounts with 250+ SP but, in the last week there are about 30+ accounts posting. Hard to say how many are automated but with all of the delegation to bots etc, there isn't much for organic discovery.
Until something better comes along, @steem-UA sounds like it might be a good thing.
My hope is it distributes and evolves to encourage better interaction and slowly, improve the environment to cut out much of the nonsense. Idealistic perhaps.
