I have just set up a new blog with Hexo, and made a slightly modified version of hexotagkatex to compile LaTeX expressions inside dollar signs, instead of using Hexo tags. KaTeX is a wonderful library built by Khan Academy, which renders LaTeX equations a lot faster and more beautifully than MathJax.
$H(T) \left  \psi(t) \right \rangle = i \hbar \frac{\partial}{\partial t} \left  \psi(t) \right \rangle$
It is also very easy to include code snippets like:


I like this hackability of Hexo, in part because I am less familiar with Ruby. I am going to make this my personal website, migrating from Tumbler which started to put a video ad on their page.
