would a reddit like algorithm beneficial for Nostr?

Not really. The trending list is also based upon human recommendations. This will always face the problem that humans will shy away from reposting or recommending anything too edgy, deep, or controversial, even if that's what they prefer to read themselves.

I'm not complaining I can't trend. I trend regularly. Here's the fastest way for me to trend: Post a pretty picture of food. Post a pretty nature picture. Remind people to stack sats. Post a selfie of my face, preferably without makeup or filters and facing the light.

A trending algorithm is precisely what its name implies: a system designed to calculate which posts are gaining traction. There’s no hidden sorcery or manipulation at play. These algorithms simply reflect patterns of human engagement, serving as a mirror to our collective interactions and interests.
