So far scaled seems nice to get the little ones higher up. AFAIK you can’t pre-make custom lists as some communities are perhaps more fun if you go for newest (comments) but then the small ones might get lost in the chaos.
Ideally, I would set scaled top 6-hours or something?
Sync seems pretty, but has a privacy policy that harvests your user data for ads.
I love building my own uBlue image. Tinkering is done in toolbox containers, definite changes are baked into the image. Completely custom (to me) and when you get it right it will just work anywhere. If I would brick my PC/storage I can just boot up another and restore my (back-upped) home dir with very little effort.
Good for them. It’s an organisation’s free choice to pick the platforms they post and interact on, if any. Their presence is a service in itself while there are plenty of other ways to follow or reach them if needed.
