Ngo Bao Chau (with appropriate accent marks) has a blog. It is in Vietnamese, because he is Vietnamese. http://thichhoctoan.net/ I don’t know how much he writes about math because I don’t read Vietnamese. I know he writes a lot about politics, or at least used to.
Cedric Villani writes about math for Le Monde sometimes and has a blog on his website. http://cedricvillani.org/ I am not good at French, so I don’t read it.
I think 10% for living Fields medalists who blog is pretty high, and many of those living are older. (And two have basically withdrawn from mathematical society.)
You missed two blogging Fields medalists.
