I know there are different use cases for each, but generally do people prefer self hosted nextcloud, proton docs, or libre office?

Are they on Deezer? If so, look into deemix-gui.

Deezer (paid for flac - lossless files) + Deemix-gui + Jellyfin + Symfonium works quite well. Though you need to have a media server, so not exactly a drop-in replacement.

I don't own P3 Reloaded, but is this sort of like the additional content that usually comes in Persona 4 Golden and Persona 5 Royal? Shouldn't this have been included in the P3 Reloaded release?

My main point was that if there's one subreddit that should of migrated fully to lemmy... it would be them. Practice what you preach. Granted they are probably one of the larger communities here on lemmy.

You could use android phones and apps, but I would also recommend checking out raspberri pi's. They are essentially tiny computers at about the same scale as a phone. Low power usage, quiet, and you can do quite a lot with them!

Meanwhile.. At r/selfhosted...

I think that is more complicated, as the channels need to generate revenue. Additionally, videos take up much more storage, and there is no option to select an instance like Lemmy. I only see options to selfhost.

I was thinking what if we switched to a fediverse Youtube replacement, such as PeerTube. However, I don't think this would work. For one, because there are no ads, there's no money being made, and creators would have to be backed by donations. Not sure how much money that would bring in.

Additionally, the difference between a "creator" on lemmy/subreddit (creating a community) vs a "creator" on youtube (uploads videos) is that I can be a creator without hosting an instance here. Looks like if I wanted to upload videos to PeerTube, I'd need to make my own instance or pay for one. Maybe if there was an option to select an instance just like here on lemmy, but videos take waaayy more disk space and processing to stream than text and a few images. Could be cool to host yourself though.

So if I made my own Lemmy instance, and subscribed to !selfhosted, does that mean if Lemmy.world went down, the !selfhosted community is still up?

I see why they recommend not using SQLite lol.

So if I only run one Matrix/Synapse instance for my private group, does any of the matrix decentalized technology effect me? I would only have one instance, and my users will probably only be connected to my instance. Though if I'm understanding correctly, it sounds like if I subscribed to another instance, all of the chat communication on that entire instance is copied to my server as well? Does this include files? Sounds like it would use a lot of extra disk space.
