I wrote more than 500 posts on my current blog[1], and much more on other blogs I've had. The first advice I give to anyone who wants to blog is to just use wordpress, don't focus on the presentation, just on the content. Once you're like 10 blog posts in, then feel free to move the content elsewhere, but not before. Anything that prevents you from writing content is friction at this point.
Other advice I also give: write short posts and write unfinished posts. If you wanted to write perfect 10/10 content again and again, you should write a book instead. A blog is about low friction to write. People are interested in your thoughts, get them out there.
