Not really, just subscribe to communities outside of your instance.
Like [email protected]. just subscribing to this from another instance and getting updates on your account regardless where it's from. Sorry if you already knew that.
Click the home icon and set your home instance and then search for whatever you want. All links will open in your home instance and you can then just subscribe.
You only need one home instance. So you’re on lemmy.world from what I can tell. If you go to their homepage and login, then click communities at the top, you can browse all the communities (subreddits). Just subscribe to whatever you want! Then later when you’re browsing you can sort by subscribed and it’ll be just those topics
Even beyond subscribing to other communities that are also on a Lemmy instance, you can throw a wider net and use some form of fediverse software to interact with different kinds of instances.
I think Lemmy software may be a little more limited in this, as I haven't had much luck subscribing to Mastodon users on my Lemmy accounts, but I can subscribe to Lemmy communities on Mastodon and Calckey. I haven't really done much with it on Mastodon, but on Calckey I can see Lemmy posts from communities I'm subscribed to in my feed, and I can make a top-level reply to the post but I can't read or reply to the comments (unless they're replies to mine) without going to some version of Lemmy to view the rest of the post.
Still, that makes it pretty convenient to scroll through my own Calckey as well as Lemmy, Mastodon, Kbin, Pixelfed, and seemingly basically whatever else I could want. Sure, sometimes I have to switch sites to engage with the content, but that's as simple as clicking a link or at worst navigating to the post again on the site. With the pace of most instances, that's not hard to do
It's also not oversaturated, so people will actually see and interact with what you're posting, and yet if you cast a wide enough net you can get continuous content to read if you really want to.
I guess the point is, the more you take it into your own hands the more it can do for you.
No need to register. You can just subscribe to their communities with your current account. That’s part of what makes federation so handy. I’m on Reddthat.com but you can see this comment even though you’re on lemmy.world.
Subscribe to more communities. I have like 50 of them from many different instances and it's always new content. Make sure to set filter to Last Day or Last 6 hours.
Lemmy.world is the largest instance now I believe with tons of communities so start there.
Honestly, this was helped simply by subbing to a lot of different communities. Each day is a fresh feed. It’s not up to Reddit’s “every single refresh is a brand new front page” level, but it’s enough to be able to scroll for an hour or two each day.
