Moderation for adults is gonna be tough
Who is going to submit to being under someone else’s control
There are lots of tools available
All require discipline to use consistently

I have my own organizational scheme to reduce distractions
No notifications on the desktop, Three hidden panels: Time/calendar/weather, Launchers, Virtual desktops/window switcher/system tray Different browser & email for different tasks
Virtual desktops Money, doctors, work
Music, books, games [no email or browser] News, critique of peoples opinions,
Forums & sites I’m testing, repair info, linux stuff

All the tabs on the different browsers relate to the purpose of the VD
If I miss, I move whatever it is to where it “belongs”
Keeps me from being stuck doing one thing too long or ignoring things I should spend time on
