The resources required by federating depend on how many people follow each other across those two instances and how much these post. Just existing and theoretically federating doesn’t need any resources if there’s nobody following, assuming threads isn’t doing that different from everyone else.
For each post a user makes on your instance, it sends that post to each instance where someone follows the poster. There’s no automatic sending to every known instance of every post on your instance.
Every image on the federated timeline. It’s a lot if users on your instance follow many other users.
It depends on the country you’re in I guess. In Germany, and other countries as well I guess, you’re not liable for stuff others people post on your platform as long as you react to reports and actually remove that shit when it’s brought to your attention. You don’t have to look at your instances media folder 24/7
Yes, it’s possible. It requires some knowledge in server administration though, you can find the specifics at the Lemmy GitHub page.
Unfortunately not. I think some areas have hashtags for that kind of stuff and someone is working on a new platform, but it’s not there yet.
It think it’s a fire and forget kind of app, so I wouldn’t expect any updates besides occasional dependency updates.
The F-Droid app is basically a browser that lets you stay logged in which is quite comfy.
Joining the channel and ask would be the most straightforward way I think. I kind of misunderstood your initial post. I know there are several different “Fedimins” communities, but I only participate in one that’s specific for German instances (of all kinds).
There’s also https://socialhub.activitypub.rocks/ Idk if they have a matrix room/space
Only thing that comes to my mind is MariaDB and “siblings”, didn’t know it’s that common.
Didn’t see it back then, just came across this on mastodon today. Sure they are competitors, given that nextcloud started as am owncloud fork, but they probably monitored ownclouds development closer than everyone else.
