I used to do this when on Windows too: C was for the OS and apps, D was for user data. The same principle here - separating OS from data is a game changer - and even easier on Linux I think. Makes it so easy to wipe a partition and try something new.
Honestly, it doesn’t really matter that much. 99.999% of my content I see comes from the people I follow and what they post and boost. Start by following people that interest you-and the rest just happens.
I’ve been walking away from Christianity for more than 10 years. I’m at the point where I just cannot stand anything Christian - I don’t want to see, hear or think about it. I definitely get your reaction.
I, too, looked high and low for this. Switching credit unions every year or so when they’d stop offering access. I finally gave up and started using Plaid. They grab all transactions from all my various accounts for $2.16/mo and shove them into Moneydance. Not what you asked for, but it works.
I ran a Pleroma instance for a while. I gave up because the application support wasn’t great. Now I run a mastodon instance - and the app support is much better. The resource usage is a non-issue.
I think OP made an error in stating you had to be 18. The oldest living person ever was 122 (as indicated by Blamemeta). As long as you are allowed a few pre-18 births, you can get to 7 generations). At 15 years old you can get to 8 generations.
I have 4 spinny disks in my NAS. The tile the server is sitting on makes more noise than the drives. I wouldn’t worry about it too much.
