I suggested this on a post by @MenO (edit: it was his Snapie project, not a personal post), but I'll add it here, too. A feed with "most reblogged posts" might be useful, especially if it had an algorithm to skip counting low-reputation accounts and accounts that reblog more than they post. Something adding value to curation would help content discovery overall if it were properly highlighted on frontends, and had some basic abuse-prevention measures.
