It doesn't take too much technical know-how to build a site. Basic HTML+CSS+JS is enough really. Writing, editing, visual design, UI design, - it all requires way too much expertise in comparison. You have to be a creative let's say 80% of the time and technical for about 20%. Reducing the last 20% only wins you 20% of the effort. But! by concentrating the technical expertise in your own head you get another level of freedom as a creative person too.
I was writing on Livejournal, habrahabr, Codrspace, and Medium before I went stand-alone. And the main reason was not ideological but rather practical. I wanted to make interactive illustrations, quizzes, and puzzles for my pages. I wanted very specific very custom things no platform would provide.
And that's why I went small web. Small web but full tech. I enjoy my creative freedom by employing let it be modest technical expertise but exactly in a way I want to employ it. And I think, investing into technical skills to get creative freedom is well worth it.
