A personal note to the team, as Facebook is very much a manage-your-own-journey company: I would strongly recommend you look into professional application, as in, Workplace.
A. that means a free trip to London for you, which is always cool. You get to meet more people with whom to joke: “It’s in the middle of a swamp! — I know — Why?! – I don’t know.”
B. there are tons of applications, roughly empowering internal equivalent to Coursera. Any solution that I know about (and it’s alas a lot: worked for 20+ companies) is bad, expensive, dysfunctional and impractical.
Getting people to use video to document their workflow, think about edge-cases, etc. is the most impactful thing I can imagine because it introduces billions into structured logic in their tasks, allows them to step from code-as-Excel-spreadsheet into code-as-a-system.
Workplace is already teaching a lot of businesses to be open, transparent, interest-driven, to record interaction for later use without closely-defined audience, etc. That happens a lot through Workplace videos — in spite of that tool being very feature-poor. Adding editing, slide-control and later something closer to choose-your-own-adventure, tests, etc. that would be incredible.
I hope you can demonstrate that there is a lot of great things to be done with interactive videos.
