Okay, it’s actually 18955 at the time of this post. I’m looking at https://lemmy.fediverse.observer/list and lemmy.world has already passed beehaw.org by a large margin for second place.
Can’t wait for this place to start filling out!
UPDATE: 5 minutes after the post, it’s now 19061. Officially more than 19000!
I’d click on a post in a Star Wars or LOTR subreddit with hundreds of comments and it was always just bots and people replying to bots with lines that triggered more bots.
