I recently redesigned my own blog (https://minimaxir.com) during some experiments into how well modern LLMs can be conditioned into not outputting the stereotypical telltale designs of web vibecoded slop; it worked well enough (although more difficult than expected) and "how to design a website using agents that doesn't look like an agent made it" might be a fun topic for a blog post as there were a few gotchas.
The main reason I did the redesign is because my blog is running Hugo + PaperMod theme, which is becoming too popular and it makes blogs no longer stand out. There were also a few features/shortcodes I wanted added (better video support, better sidenote support, etc) that give me more tools for blogging.
