No algorithm is cool and shit, but this is what my featured feed looks like: 
Discussion
There is actually an algorithm, based on who received the most zaps in the past 24 hours. It's very primitive and basically a placeholder while I work on a better algo
I really appreciate you continuing to develop satellite, it is the best web client by far. As an aside, I've launched a free strfry relay, you are welcome to throw it into the default relay pool if you want: wss://n.ok0.org
It sits on powerful hardware and may make a difference for AU/NZ folks. It also blocks shitcoin bot spam
Cool! I'll add it with the next update
I use a Japanese relay for messaging, notifications, etc. I'm not sure if this has any impact on how you view global.
Wonder what algo 🛰️ uses for Featured? 🤔
According to the dev it's a basic placeholder based on zaps:

I can't complain too much, I almost exclusively use Satellite. But I do look forward to it being improved.
It seems sort of ok, I never even clicked on it before this lol, I'm quite skeptical of any featured/trending client section lol.
Hoping there's more discoverability of content / users in satellite based on group membership and likes and whatnot interconnectivity in future:)
It is one of the only clients that supports "communities", though sadly they are barely used on Nostr as a whole so that's not very useful yet.
My following feed is getting better now that I've been following more interesting people, so that helps too. I agree it's good to be weary of featured/trending client sections, though they do help when you're new and have nothing to interact with.
Personally I hope groups eventually take off Reddit style.
