It strikes me as a strange idea:
- Material design uses lots of UI idioms that work well for an OS (user will learn them), but not so well for a website (that needs to be instantly usable on first use, or user will leave for a competitor). The overflow icon (three vertical dots) is one example.
- Material design is the Google "branded" look and feel. No sane web business would want to give up their own look and feel. It even strikes me as a weird choice for @minimaxir's personal blog. If you're going to skin your site with another brand's look and feel, why not Uber? Amazon? etc?
- It's never going to feel quite right. Uncanny valley between native app and website.
