I'm a relatively new member of Reddit, and I was just wondering what things have changed on this website over the years?

I've heard multiple people (who are elder Reddit members) say that Reddit is not how it used to be. They say it's gotten worse. I understand that Insanity Wolf has gone way downhill.. I dont need to be a member of 5 years to realize that.. But what other things have gone downhill since you were a new member? I'm curious because I want to steer away from that path and remain loyal to Reddit.
