Good points. Though I disagree with your point about articles that don't trend. You're right in most cases, but I've seen so many excellent posts fall through the cracks because of the game like nature of content curation. There is definitely an element of luck and timing, especially for newer members who don't have followers or steem power. The only thing I was trying to call into question was the way content is handled long term. I feel like there should be some sort of way to for popular content to remain visibile longer than 12 or 24 hours, or even 30 days.
It's easy to forget that were still in beta. I know a lot of issues, like this one, will be addressed in some way at some point in the future.
