I’ve noticed that activity frequency in this instance has slowed down compared to late 2019 or early 2020. Is that just me?

Maybe I’ve just been posting crappy posts lately (I’ll let you all be the judge of that), but I’ve noticed marked decreases in both votes and comments on both my posts and in general, and posts by other people seem to be drying up. I remember being able to have some pretty detailed discussions in the comments a while back, but now it seems that discussions on new posts beyond just a few comments rarely happen.

Am I going crazy here or is this instance slowing down? What could be the cause of this?
