Same here, although I go through phases of high and low activity. When I was learning to code I would write daily blog posts about problems I ran into and how I fixed them. At first I was unsure, since I thought these things were just too basic for people to care about. But writing also helped me process and internalize the things I learned, so I did it anyway. I got so many nice emails and comments over the years from people who found some random tip I posted helpful for their own projects.
