Funny: I was forced to write a blog post every month by my CEO, about a decade ago. I did it for about a year, and some of these went to No1 on HN (for example this one [1]). Just searched for it, and although the company is turpor, the blog is still alive. Looking back it gives me an insight on my opinions at the time.
