A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title

- Adhere to Lemmy's Code of Conduct

Lemmy is a federated link aggregator and forum. Kind of like a hybrid between email and Reddit. I'm a member of Lemmy.zip, but I'm posting on another Lemmy instance (I forget where this post is, Lemmy.world, right?). Lemmy.zip and lemmy.world are "federated", which means if users on one instance interact with users on another, both servers will sync this activity. Lemmy.world will accept lemmy.zip user posts.
And user names are only unique for a server. Just like "chunkylover53@aol.com" is a different email than "chunkylover53@hotmail.com".
Community searching shows the community name and the server where it's hosted. Even though I only have an account on Lemmy.zip, I can subscribe, comment, and post on communities from other instances, as long as lemmy.zip is federated with them.
Recently, Beehaw de-federated from much of the fedi-verse. This means their software works the same, but prevents their users from interacting with the rest of the community, and the rest of the community from interacting with their communities and users.
It's complicated and annoying, but necessary to be federated to prevent the fate of Digg and Reddit.
Also, one instance could require email and 2FA to be safe, and choose to de-federate from an instance that has no verification and becomes full of spammers. Or, someone could create a Lemmy instance that requires verification of identity (like AMA used to do, or the old Twitter checkmark), so if John.Oliver from the "Lemmy.OnePercent" instance posts, you know it's the real John Oliver. There's benefits and complications from federation.
So if I'm understanding it correctly, Lemmy is the Federation and .world is the instance? And then within that instance are it's own communuties?
Not quite. Lemmy.world is the instance. I'm from the instance lemmy.sdf.org and I also hang out on feddit.uk . The instance names are just URLs (.world, .uk, and org are all like .com).
Handwavy explanation because I'm fuzzy on details: Federation is the magical interconnection between instance lemmy.sdf.org and instance lemmy.world that allows me to see posts/threads/users on the lemmy.world instance .
Hmmm...I think this is the best explanation I've had so far.
I certainly don't mean this negatively, but I get the impression a lot of the people here that actually understand it are also bad at explaining it to normies like me. And people like me are very much in the minority at this stage in the growth.
Aww, thank you.
It's a hazard of really knowing what you're talking about that leads to overestimating what other people know. I don't have that problem 😉. Relevant xkcd: https://xkcd.com/2501/ .
@fluke is this a joke?
@fluke in case this is not a joke, yes instances host communities, but the lemmy.world is just a domain name. Federation just means lemmy.world and another server/instance such as geddit.social can share and exchange communities, comments, and threads they host with each other. I'd be happy to answer additional questions you might have, but I'm not as expert as I don't share links in that format much.
Is what a joke?
