Not just frequent jokes, but those annoying ever-repeating jokes. Like as if 80% of users were the same person. Before opening any post on Reddit, there is a good chance to be able to correctly predict the exact content of a significant portion of the comments. I get that it can be funny to an individual to come across stuff like "I also choose this guys wife" or "And my axe" more than once. But for people like me, who did not just start using the website, it is really annoying to come across the same jokes literally hundreds of times.

This goes hand in hand with the general idea of a "Reddit hivemind". Depending on the subs you visit, you can see that Reddits userbase is actually really diverse. There are people from every demographic with all kinds of different life experiences. But in a lot of subs, anytime a woman is mentioned there is a flood of people acting like as if there are no women on the internet and as if no person using Reddit could have a girlfriend. Again, I get that it can be funny once or twice. But when the idea that every user must be a typical "Redditor" gets repeated all the time it's just annoying. Needless to say that I don't look forward to being called a "Lemming" on this site.

Also, repeating comments on the same post. Obviously you don't have to read all the comments if there are already hundreds of them. But if there are too many comments saying the exact same thing it just gets harder to read them all. So it would be nice if people would look whether the point they want to make maybe has been made already. They can increase that comment's visibility by upvoting. No need to make other people read the same content multiple times and by that make it harder to read different comments.
