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)

Yeah I am a software dev and was even confused for a bit. Reddit has /r/all and things that make it easier to find subreddits, I still struggle with lemmy sometimes. Sync made it a bit easier, but I wish I could seamlessly browse all instances and their comments under 1 profile
