I bought a year of Medium subscription but I don't think I'll renew it because their suggestion algorithms are bad. If you click on one programming-related article you will be forcefed exclusively the most boring programming crap ever until the end of time. There's like a million articles on there about "programming habits" and "genius daily routines" and "productivity hacks" and "programming career advice" ... all very boring content.

A major issue I see with online blogging is the glut of tech and computing content drowning out everything else. The barrier to entry for self-hosted content also means most self-hosted content is tech oriented.
