One would think it ought to be possible to automate generating these overviews. Or has it been automated and is it being posted with a non-service account because it's partially but not fully automated?
Pretty sure Dang has some nice scripts that generate this, and I expect he does a little manual pruning before posting it. He’s very precise in his choices, definitely applies some intuition/judgement. We can’t losslessly compress him — yet!
