For what it's worth, I've found it ok (not great, but just ok) to write in Colab notebooks (maybe because I use it at work and I'm familiar with it). Here are a couple of such "blog posts" (which are basically just explorations for myself, but still clean enough to share): • https://colab.research.google.com/drive/1kEmqjgjudlmPwDReTH9-RO86LvBf92YF https://colab.research.google.com/drive/1kEmqjgjudlmPwDReTH9... • https://colab.research.google.com/drive/1wbktvb8XWISitThnpRA5_MLZh0JaKcK6 https://colab.research.google.com/drive/1wbktvb8XWISitThnpRA... • https://colab.research.google.com/drive/1vsEE7XooIF1jHZKWZbElm5xUyZewr17Z https://colab.research.google.com/drive/1vsEE7XooIF1jHZKWZbE... Pros: Can just type Markdown and LaTeX math; don't need a separate step to convert to HTML/CSS/JavaScript. Cons: URL is ugly, code can only be Python (I think?), the UI is janky, can list lots more. But the friction was low enough that it got me to write at all (and move on without endlessly fiddling and never posting), and that's the most important thing for me. I imagine if I were more comfortable doing everything in Javascript I could use Observable notebooks, as suggested in a sibling comment.
