My Law of Living Room / Internet Parity states:

Whatever is happening in your living room right now is also happening somewhere online.

Watching TV in your living room? Someone's doing it online.

Playing board games? Discussing fascism? Happening online.

Fighting with your spouse? Having sex with your spouse? Fighting with your spouse after they caught you having sex with your not-spouse? Yup, online now.

Writing a thank you card? Worrying about growing old? Plotting to start a diet? Listening to your favorite CD? Planning a camping trip? Reading a book? Dozing off? Playing a video game? Decorating a Christmas tree? Looking at family photos? Talking on the phone? That's all happening online too.

This is the fundamental greatness and scale of the internet at work.
