Don't take me wrong, I really appreciate Khan and I've learned quite a bit from his videos, but I am not seeing the technical challenges in running the website.

Don't take me wrong, I really appreciate Khan and I've learned quite a bit from his videos, but I am not seeing the technical challenges in running the website. My opinion is the challenge with Khan's academy is not a technical one, but how to scale the teachers/presenters. Khan is a great teacher, very knowledgable and engaging, but how do you find people like him to take over the other subjects.

A few things we're currently working on building: – The next version of our personalized learning dashboard [1] to make the UI more consistent across subjects and to help people learn better – Improved knowledge models so we can better know what you know and don't know [2] – Better tools for our content creators to allow them to make thousands of engaging, interactive exercise problems without knowing how to code [3] – A major revision to our iOS app to let students practice skills on the go (or in a classroom with iPads!) – Infrastructure improvements to make the site more reliable and faster for our millions of visitors every month [4] There's a ton more that we want to do but haven't had a chance to even think about yet. Not all of our work is technically interesting, but a lot of it is, and it's easy to find technical challenges if that's what you're looking for. (As for new content, we're working on partnerships with other organizations [5][6] and have many new content creators in other subjects [7]. We're obviously working hard to find ways to make more great content.)

  Another example of something technically cool that we built recently is tinyquery, a pure-Python reimplementation of Google BigQuery suitable for very small data sets, which we're using for (fast) integration testing when building pipelines on top of the BigQuery API: https://github.com/Khan/tinyquery https://github.com/Khan/tinyquery
