One day, I'll have kids, and my kids are going to want to go on the internet. And this is what I'll tell them:
The internet is like Fairyland. It is a wondrous place, a place of many marvels and many opportunities.
It is also a dangerous place, with strange rules that often seem arbitrary — to navigate it, you have to learn its fairy-logic, and learn to speak its language.
It is a place of tests and trials — the folk can be cruel, pointlessly so, just because it amuses them. It's often not personal, even if it seems like it is. The worst are the Trolls, but they will lose power if you don't engage with them.
It is a place of illusion and lies. Everyone wears a mask, and not all the masked people are actually people. Don't believe everything you see or hear, for illusions are everywhere.
Time moves differently there. Entire days can go by, seemingly in an instant.
Do not accept anything you're offered, and be very careful to whom you tell your True Name.
