I have viewed my feed in gossip (gossip lets you view a relay's global feed) and it was tailored to me.

One note seemed strangely irrelevant (not very connected to me nor reacted to much).

It appeared to me that as I went down the feed, there were fewer events per time period, and those had to be much more popular (based on reactions).  Which makes sense.

I'd love an English description of the algorithm.
