The early days of WSB were much different compared to what it is today. It used to have some really smart people doing quality research and putting their money where their mouth was with large bets. As it grew and more new traders came in, the new traders started pumping out half-baked ideas to make a name for themselves and the other new traders followed and lost their life savings. Honestly I think that the focus on memes is partially to blame.
All of the people that were originally in WSB left and went to a couple of smaller subreddits and/or a collection of small discord servers.
