Yet this point was completely missed by Louie, an important SI staff member, who apparently thought I was advocating for "the SI", XiXiDu-style.

I never learnt this stuff in school and my current focus is on improving the math education that I missed rather than rules of grammar. I promise that I will teach myself how to write correct English in future. But right now I don't give it top priority so I hope you will tolerate some of my mistakes for the time being.
