I’ve been here a long time, and it slowed down significantly a few years ago. Then again fairly recently took another blow. In my opinion the primary thing that knocked it down, and thinned participation, was people who were on the site who didn’t want debate.
Some key jellies were banned. Some jellies have passed away. Some jellies left because of personal attacks. Some jellies left because they felt too addicted, and gave it up. Some jellies left in protest to moderation being very hardsh. With all of those people gone, and very few people promoting the site, just through attrition and a snowball/domino effect, the numbers have dwindled. Auggie used to do what she could to promote the site. She was the one that got me to come here.
