No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

Usenet has its own protocol (NNTP) where digests of messages get passed from server to server, eventually making it out to all (or most) servers that host a particular group (like alt, sys, gov, etc.). In essence, it’s a federated digital bulletin board of bulletin boards. Many servers don’t participate in some groups such as alt.binary.*.
Usenet pre-dates the world wide web, and even pre-dates Gopher. It was designed such that a Usenet server could spend most of its time disconnected from the Internet and accumulate local posts that would then be federated in a digest when the server dialed up and connected to other servers.
The main NNTP network eventually made its way to a centralized web-accessible service and most places that used to provide an NNTP server (which was most ISPs in the 90s) eventually shut their servers down and only provided gateway and email services.
The protocol still exists though, and there’s still a small connected network.
In reality, Lemmy is the spiritual descendant of Usenet.
...Would this have been local posts of an individual, or sometimes a group in a LAN or something? The way you describe it here puts me in the mind of recent stuff like Scuttlebutt, albeit that's more clearly individual-focused.
What’s scuttlebutt?
And no, not individual and not LAN. WAN. A Usenet server could easily service hundreds of folks if not thousands. It would collect all their posts and then aggregate upwards.
This gives a brief overview of Scuttlebutt with a link to a more technical breakdown.
That said, I remain confused by the other person's description, as I'm not sure how it's accumulating posts while "disconnected from the Internet". I follow how it works when connected, but not so much how it would work as they've described it, at least in the disconnected circumstances, unless it's sorta how I asked.
The Internet is a network of networks. Nowadays, everyone tends to have always-on connections to the entire thing, but back in the day, many of the networks spent a lot of time disconnected from each other. Usenet was designed to mostly transparently handle this by the local network having an aggregating server that would collect all the local activity and share it with other Usenet servers when it could reach them.
Remember that even the local activity was people connecting with teletype terminals and dialing up over modems from remote systems. Long distance trunking fees were a big deal, and Internet routing had to deal with the possibility that there was currently no route to the destination address.
Thanks for clarifying! So it does work roughly as I was thinking, that's cool!
