At first, it looked better. 

Higher-quality posts and less general social network posts but they were just lower in the feed.

I only saw 18 posts from the usual trending users on Nostr and mostly notes I had already seen. So there is no noticeable difference for me.

As I have not interacted yet with many people, this is probably not bringing value to new users yet as they see the same as the Trending 24H notes.

I would find an algo surfacing notes by topic and quality much more useful. For instance, find the top 10 artists, writers, musicians,... or recommend more.
