I resonate with this. I enjoy reading people's technical, artistic and personal writings. How they built, solved, or learned something new. Their favorite tools, workflows. Favorite authors, concepts, interests. @simonw is a great example of this kind of openness and working in public. I'm learning how to do that in my own way.
It makes the world friendlier, more welcoming for beginners and life-long students. It also creates a sense of community and human connection, which is often cynically exploited in today's society.
There are several problems with this. First, a lot of people including myself don’t enjoy writing. Then there is the problem that these days people will give you a hard time for something you wrote 10 years ago. I don’t really feel I did anything wrong but I don’t want to have to spend time and energy on explaining myself.
So if people enjoy writing , they should do it. But also be less judgmental about other people.
