I hope Medium have stayed invite-only. It's really hard to keep the content high quality when a lot of people flood in. The atmosphere changes, and that changes the culture and everything.

And I'm really sad that Signal v. Noise has moved to Medium, too. I miss the "Happy Monday" every time I come to the site. It feels like walking in a local bakery and having a friendly chat with the waitress. It's a warmth and sincerity I seldom find in today's websites.
