I thought communities synced over instances so if an instance goes down, communities are still accessible. Is this not true?

This is not true. ActivityPub (the protocol Lemmy instances use to speak with one-another) does not intend to be a redundant, distributed datastore. There are a few reasons for this. One is practical. It needs to be affordable to start a new instance. If the requirements for starting a new instance entail mirroring significant parts of the fediverse (a network of over 2 million users and 22,000 instances) it would be impossible for anybody to do it unless they were Google/Facebook.

Another has to do with trust. A community has a home. That home is chosen (ideally) because the admins can be trusted. That instance is the universal source of truth for that community. If communities didn’t live on a specific instance, they would be vulnerable to various forms of hijacking. The home instance has the final say on who has permission to comment, and who has permission to perform moderator actions. None of these actions could be trusted if they weren’t cleared by the home instance first. Third party servers perform basic validataion against the currently known ban list / mod list / etc, but this could easily be spoofed by malicious instances.

When an instance goes down, it is kind of similar to a netsplit on IRC. A queue of outgoing messages build up on your instance, which can be seen on your instance. Queues of messages queue up on other instances, which can be seen on other instances, but they won’t be synchronized until the destination instance returns (this depends specifically on which inbox the messages are directed towards - I’m not particularly familliar with the specific implementation in Lemmy).

Finally (though not really), ActivityPub isn’t designed to be a broadcasting protocol. In the case of Lemmy, and other Reddit-like clones, it effectively acts as such, but it is intended only to send messages to the places they belong. If you post a message and the subscribers to that message only exist on 3 servers, that message ONLY gets sent to those three servers, even though there are thousands of servers in the network (at least, this is how it is supposed to work in theory).

I might have some details wrong here. I’m more familiar with how Mastodon works (and how it fails) at this point after troubleshooting various problems on my instance.

For the love of god, listen to some Citations Needed and stop self-congratilating your media literacy because some fucking dork with a website tells you the New York Times and Washington Post aren’t biased.

X11 used to require very cumbersome MANUAL configuration, where you would specify the exact parameters of your keyboard, mouse, monitor, and other peripherals. If you accidentally ended up overclocking your monitor it would melt. For at least a decade, it has been able to run with no configuration file at all, but in the 90s/early 2000s you had to produce a unique >75 line xorg.conf file for your specific hardware.

They could, but they will develop a very poor reputation if they do this for frivolous reasons.

It is a mixed bag. This can be useful in some cases, but it can also be very inorganic. There are tons of accounts on Mastodon which mirror content from Twitter. They might even be run by the Twitter user themselves, but if there is no interaction and the user doesn’t even check them, they just end up becoming noise.

let them fight

For now, if it turns out to be shit, you can just join a different instance. Perhaps leave a note in your old bio which directs people to your new account.

> Federation means it’s almost meaningless which instance you register with, and as integration between instances and other Fediverse apps gets better it will just become more and more meaningless.

IMO, this couldn’t be further from the truth. Different communities have different priorities, principles, and technical requirements, and will take different approaches to controversy. Some communities are low-profile and laid back. Others are magnets for abuse and may require additional moderation, and even technical changes, like disabling image embeds (as one example) to mitigate harassment. Some are filled with avid shitposters, while others insist on the utmost degree of civility. Some have advanced requirements for operational security. Some want to protect broad access to the network at all costs, while other would rather accept a couple blocks rather than ban their own members. Some might be focused on video and require an instance that can handle the additional bandwidth and storage requirements.

Who hosts your instance is important. The jurisdiction your instance is housed in is important. If a community requires special accommodations for accessibility or other reasons, that is important. If you need moderators / admins who understand your native language, that is important. If an instance wants to go above the technical level and do things like verify users (kinda like journa.host) that makes an important distinction from your typical instance.

In the beginning, we won’t know who’s trustworthy, but this is the Internet. There will be controversies, and we will see how various admins respond to these controversies. Over time, they will gain reputations, both good and bad. It is best if somebody who already has a good reputation, like a respected mod from another community is able to operate the new home for that community.

For now, it probably doesn’t matter where you end up, but as time passes, it is good to keep an ear to the ground and see how things develop. Eventually you will find a solid niche. This is a problem even the fanciest join-xyz-fediservice website can’t really solve, but it is meaningful.

The politics of folks like RMS (personal issues aside) were far above average, but the Free Software Movement was very steeped in liberalism from its onset, and that explains many of of its present shortcomings. Its biggest failing was to believe that Free Software would ultimately win on its merits. In the early days this was understandable, when free software was often playing catch-up to replicate the functionality of established commercial offerings. When the GNU project was just a C compiler you could install on proprietary UNIX systems to dick around with.

Today though, Free Software is more often than not superior to commercially available offerings, with the exception of some niche industrial segments. But still, Free Software adoption by end users remains incredibly marginal. No matter how many merits Free Software stacks in its favor, the “Year of Linux on the Desktop” never comes. We are still drowning in proprietary iOS and Android phones. The overwhelming majority of PCs still ship with Windows. All of it deliberately engineered to become E-waste in a couple of years.

Folks, this won’t change unless we take over the factories where these PCs and phones are manufactured.

Coming up on 30 years!
