Don’t use the “all” feed. I only use it to discover new communities (but there is also a specific community for that).

For my daily browsing I exclusively use the “subscribed” feed.

Edit: the community I mentioned is https://lemmy.world/c/newcommunities@lemmy.world or !newcommunities@lemmy.world

Because the people who left reddit for lemmy are the people who left digg for reddit, mostly. So old Internet people. Hence old memes.

Edit: my phone decided digg should be high. IDK.

I find it quite funny that you sometimes see posts here that say that they are glad that all the smart people left reddit and the cringe people are now all on reddit.
All followed by the most cringe boomer humor i have ever seen. Like some shit that wouldn't even get upvoted on /r/funny

Don’t subscribe to those communities?

Because you subscribe to communities that are full of old memes and/or because you browse 'all' instead of your subscribed feed.

As to why the wider Lemmyverse has too much of that sort of stuff, it's because a lot of people are trying to recreate Reddit instead of building something new. Or because they're trying to kickstart the something new by posting plenty of content and, inevitably, much of it is old.

Post stuff you want to see. Engage with stuff you want to see.

Some people who like to post memes also like to post them in multiple communities, and crossposting can be much more obvious here than on reddit

I mean, it's the low hanging fruit content. It gets done engagement, some amount of almost nostalgia, but doesn't require much work to post. It's not the end of the world, it just comes in larger volumes and takes up quite a bit of "all". Honestly blocking some of those communities would probably work well to clean up your all feed if you wanted.

We’re kind of at the tail end of a nostalgic meme trend. !antiquememesroadshow@lemmy.world blew up about 3 weeks ago, it spread to the other meme communities, and everyone was having fun with posting crusty old memes.

Block those communities

It's a phase! I swear!

Your subscription list must look very different from mine.

It is all the content that some people have.

Unsubscribe from the meme communities. Problem solved.

If I could mandate one rule for the fediverse that it didn't already have, it would be a hard ban on reposts, especially those undated Twitter screencaps that took over entire subreddits the last few years.

If I may suggest, start following federated pages too. Each social media has its niche, and now, with federation that allows direct communications, it's the perfect opportunity to find a social media whose features you like (which you seem to have already gotten), and curate your contents so it's perfect for you without depending solely on your chosen social media's niche.

Probably because the average lemmings is way older than the average redditor.

It’s because a lot of people here are people who miss the earlier days of the internet and are trying to recreate that feeling. I’m not that old but it’s got me feeling nostalgic so I enjoy it

It's a way to add content and (hopefully) build interest in the system. It's also a way for Lemmy users to show they are just a little different.

Yeah, I need to move off of all and start curating a subscription list. Before hexbear was federated there wasn't any need.

You can block the meme communities, then you won't see those posts in your feed.

I sort of enjoy seeing the ones I had forgotten about.

new way of transmitting thoughts, through images or bots

I only use the subscriptions feed, so I only see what I want to see and that removes this problem.
