I'd think an ideal trending algo would be based on some combination of zaps, comments, likes, and length of comment threads.

Maybe multiple feeds.

- "Most zapped" will probably show new work by devs and fun Bitcoiner posts

- "Most liked" will show posts that the plebs like

- "Most comments" will show posts from accounts with many active followers

- "Longest threads" will show you where the fun discourse is actually happening
