After endless timewasting I decided I should use ikiwiki for my blog. It pretty much has everything I want, and requires minimal effort to use. I think there's a few configuration things left to do on the site (making comments/login for it work) but once they're done it should be good to go. There aren't many premade themes available. I quite like this simple styling using a CSS I found. Maybe tweak it and templates overtime but it's fine for now.
It's also a wiki, although probably keep most of my wiki content on tiddlywiki over at fondoftea.com ☕.
