  • Two likely possibilities with further detail about each below:

    1. The link you clicked took you to the community on the host instance rather than the copy on your local instance, or

    2. The community is on an instance that’s defederated with your home instance.

    When you view and interact with communities and content hosted on another server, you’re technically interacting with a copy of that community/content that’s hosted on your home server and kept in sync with the main copy. So if I want to subscribe to /c/technology hosted on lemmy.world even though my home instance is sh.itjust.works, I need to visit the copy on shitjustworks at sh.itjust.works/c/[email protected]

    If I went to lemmy.world/c/technology, I couldn’t interact because I don’t have an account on the lemmy.world site.

    As I said above, communities and content are copied between Lemmy instances and kept in sync across the copies. But sometimes an instance will ‘defederate’ with another, ie cutting the direct connection between them that lets them copy and sync content. In that case, there’s no local copy for me to subscribe to or interact with.

    The incorrect link is far more likely to be the issue than defederation, so whenever you run into that issue check the link and make sure it’s the copy on your instance.





  • You’re not the only one! That’s partly why I made that post- on Reddit I would make 1-2 posts a year and only got real traction with 1 or 2 ever. I was always too late for my comments to matter and I usually just browsed and voted.

    Here, the community is smaller so each post and comment matters more, and for the most part I’ve found it a lot more welcoming. I realized that engaging more proactively was a lot more fun than on Reddit, and I thought that others would probably be thinking the same way so maybe this post would help break down that passive habit so many of us have from Reddit.









  • I got started with browsing the most popular communities (if you’re on a browser, click Communities in the upper left, then pick All under List of communities) and picking the ones that seemed interesting. Then I started searching for ones that mirrored my subreddits and other interests. One thing to note is that Lemmy is growing so fast that you’ll often find more than one community about the same topic, so don’t be shy about subscribing to somewhat duplicative communities until one comes out on top.

    There are still some subreddits that don’t have an equivalent here yet, so I check back for those every few days to see if anyone has gotten around to them (I’m definitely not up for moderating myself)

    As @[email protected] posted, you can also use https://browse.feddit.de/ to quickly search for communities and see their subscriber, post and comment count to gauge how active they are.

    Welcome!


  • Oops, I’m still trying to figure out the formatting for links. Sorry!

    The full URL should look something like yourinstancename/c/communityname@articleinstancename. So since you’re on reddthat.com, for you to access [email protected], you’ll need to go to reddthat.com/c/[email protected]. If you were visiting a community that’s on your own instance, you can drop the @instancename part at the end.

    For what instances are, think of it like email. You can have Gmail, Outlook, Hotmail, AOL, or any other email client and can send messages to users on any other client since they share the same protocol/language. It’s the same idea here. Every community is hosted on a particular instance, such as reddthat or lemmy.world or sh.itjust.works. Since all instances use the same protocol, a user from any instance can see and interact with content on any other instance (with an exception I’ll get into in a sec).

    Back to the email analogy. If someone using Hotmail gets an email from someone using Gmail, the Hotmail user doesn’t actually access Gmail itself to read the message. Instead, Hotmail makes a copy of the message on its own servers for the Hotmail user to read. With the Fediverse, same idea - if you see content originally posted on another instance, you’re technically seeing a copy of that content hosted on your instance. And if you interact with it, like making a post or commenting or even upvoting, you’re doing that on your copy of the content, which is then synced back with the original copy. From there it’s pushed out to all the other copies on all the other instances that are synced to the content. This is what Federation refers to - separate instances hosting different content that all communicate with each other to make a single community out of all its different parts.

    The exception to all this direct communication is defederation, which is when two instances don’t talk to each other directly (usually one cuts off the other). This means that users on those instances can’t see or interact with content on the other instance. Defederation is a pretty extreme measure and its use varies instance-to-instance based on the admins. Some instances are pretty quick to defederate (such as Beehaw) but most see defederation as a last resort.

    I hope that made sense!
