It is probably due to a number of people stopping using their alts after some instance hopping.
Also a few people who came to see how it was, and weren’t attracted enough to become regular visitors.
Curious to see at which number we’ll stabilize.
Next peak will probably happen after either major features release (e.g. exhaustive mod tools allowing reluctant communities to move from Reddit) or the next Reddit fuck up (e.g. removing old.reddit)

In my experience, Active and Hot have been opposite extremes of freshness. Active shows posts that are more than a day old, and Hot shows posts that have no comments and are just a couple of minutes old.
Not to say it’s all bad. Your post was just a couple of scrolls down on my feed.
I vote for sorting by new comments… I’m generally entertained with this setup
