Mathematicians use WordPress quite a bit for publishing math research and notes. In fact today I just helped to fix some LaTeX issues on Terence Tao (陶哲軒) math blog. I’ve always regarded math as the highest, purest form of human intelligence. Tao is one of the most famous young mathematicians in the world today, so when Matt asked me to help him, I was more than pleased and worked late into Friday night to fix those issues.
Note: LaTeX support is available on WordPress.com blogs.
On your self-hosted WordPress blog, you need to install LaTeX plugin.
