Writing takes practice like any other skill. When I go back and read my earliest blog posts, it's a total cringefest. A stumbling start is nothing to be ashamed of, and is a requirement for a strong finish.
Are you only interested in blogs from people with and about technical skills, or is any focus tech related all good?
It's a shame, because I see a lot of value in writing down one's thoughts, e.g. more easily noticing gaps in knowledge of a subject.
