> Khan Academy used to have [...] but for some reason they removed it
I'm quite saddened by all the stuff that's been removed from Khan Academy over the years. Most of the non-maths content has been removed. The knowledge graph has been removed, etc. I've stopped donating to them because every time I use it, the experience has gotten worse.
