I am not sure if you look at the comments even , but in any case, you can always find good authors by checking @curie votes every day. Because @curie votes exceptional posts and you can hand pick some authors from there. Alternatively you can join the curie trail as well.
And I was doing a Caption Contest of original arts, which was stopped because of lack of enough rewards. If you will be willing to sponsor ( we just need one vote in a week of whatever value you decide), then I can continue,
And my personal favorite @prabalmallick, worth to have a look. People like him probably quit or do not get encouragement here.
