I joined this site a fortnight ago today.
I did not have a clue how it worked, or about its lore and culture.
Now, it seems intuitive - though not because I am adept but because networks and protocols are familiar and practical things.
We use them all the time: www, mobiles, emails, etc.
And this place is structured to encourage calm civility.
It was Twitter which was strange and, in many ways, inhumane - rewarding clicks and rage and vileness.
We just got used to it.
And now we are out.
