What are some of the biggest changes in discussion from Jan-Feb 2021 to current day on r/stocks? It seems this subs traffic has fallen since

I wondered if the sub was slower in July 2022 than it was in Jan 2021 and got shocked by just how much traffic and posts have slowed down. Apparently this sub had 450+ posts in a single day on one of those late Jan 2021 days. Nowadays the sub averages in the 15-40 posts a day in June-July 2022. There was a 10.4K comment day on the sub in early Feb 2021 now the sub averages about 1000-200 a day in June-July 2022. Here is site I found but there are probably others out there

That is such a massive drop off. Where did all those people go? Was the discussions different or something in those days for there to be so much posts/comments?
