A blog post is a very long and complex search query to find fascinating people and make them route interesting stuff to your inbox

The title says it all.
The essay says more… and rings true with my experience.
I had written an essay about Ivan Illich and systems thinking, a topic I had never found anyone else intrigued by, and which magazines thought below a rejection letter—and the internet had suddenly reshaped itself so that my keyboard hooked up to the screens of a bunch of people who wanted to talk about these topics, and a little later, their keyboards hooked up to mine.
I had written for 15 years, but never before had this happened. I had conjured a minor conference! And I hadn’t even known that you could do that.
Write and publish. The more specific and true to you the better. If you have a same path of conversation twice with different friends… that would probably be a good blog post.
