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)

I used Reddit Sync for about a decade before switching to Infinity for Reddit, tried giving Sync another go after the Lemmy version released and it just felt wrong whereas the Lemmy fork of Infinity is a joy to use (and is FOSS)!
I prefer Infinity too, but was a huge Infinity fan so I guess it makes sense
