My theory is this: new Lemmy users aren’t comfortable yet, so some are looking for easy ways to begin engaging with the site. 196 is a low-stakes way to make a first post without the anxiety of a higher effort post.
I don’t think I mind it either, if it gets more people actively participating in some way. And if it grows too out of control, at least there’s a block option.
It’s labor, but a labor of love.
