A chat on subreddit /r/wallstreetbets

I have noticed how mind numbingly stupid the average redditor has become, but I didn't realise new accounts amounted to almost 98%&gt;.

Well not necessarily new accounts, just accounts using new reddit or the official app. I have never seen stats about old accounts and what form they use.

But it's safe to say that reddit is far larger now than 10 years ago, probably by a factor of 10 or more.
