However I have zero discoverability that way, like I said in the post. I can write nice articles but nobody will come across them, even people that would have been interested. I'm not vain or anything if I say so myself but if I put in the work it would be nice if someone would actually benefit from it :)
This is the nice thing about platforms like Medium but they're all so commercial... I don't like that part. And I don't want to constantly market my blog everywhere. I just want it in a place where people could pick up on it if they find it interesting, and ideally where I could find such posts from others. A bit like Hacker News but then more for blogs itself.
It absolutely does not need to monetise in any way. I have a job :)
Bonus to hosting your own stuff is that you own it and no one can take that from you.
