Hmm. AntennaPod supports syncing with Next loud via a Gpodder's API, if each kid gets its own next loud account it should work fine

I quite like using K-9 Mail, it merged with Thunderbird and great things are coming for it, I think it's awesome
Well you can install it locally and get the web interface via localhost, but if it's a proper server you can access the news from your sources from anywhere and you can also use 3rd party apps in your phone to get a different interface via the API
I recommend trying the apps, especially wefwef.app
I have never seen anyone caring about usernames in reddit, I expect the same here, I just want a cool short handle, I'll get my cool short handle, not because that's me but because I want a cool, short, handle
FreshRSS, news and websites fetched your way. You can even create feeds for websites that don't provide one
You should get into Personal websites' RSS feeds. I recommend checking #100DaysToOffload if you have Mastodon or similar, they are pretty much small blogs done by people just trying to write about stuff, nothing too serious, but entertaining
My most used would be
Tusky
Tachiyomi
Activity watch
AntennaPod
Droidify
Signal
Librera Reader
K-9 Mail
KeepassDX
Bromite
That's fair! I joined apollo.town because it's small and tidy, not a lot of local communities but following stuff from there ain't that slow
