Many people know us from our free educational videos (available on our site and on YouTube). We've also got tools for teachers, school districts, and parents. And the Official SAT Practice. Plus tons of exercises and content well beyond math. A lot of people don't realize that we're a non-profit, so learning on Khan Academy will always be free.
We've got a big mission to work on generally, and right now we have a big technical project underway to get us off of Python 2 and into Go. All of that functionality I mentioned in the previous paragraph? It's gotta be converted.
Some of our site is already running in Go and we've been making the switch incrementally without users seeing the switch (plus with the highest usage we've ever seen).
