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)

Those are just cop-outs. They need to be hard-coded features on the original Lemmy app. If we have to rely on third-party apps for it, we can and should just use another fediverse app entirely.
I hope someone forks Lemmy at some point.
