PROJECT: Edit "Blockstream Office Hours" Videos

We have slightly more than a dozen Zoom recordings of various Bitcoin, blockchain, and privacy advocates from our "Office Hours" during the last two cohorts of interns. There will be more interviews and Q&A added this summer. @ChristopherA can provide links and access to them all.

We are looking to:
- [ ] Review extant videos.
- [ ] Identify major topics within the videos.
- [ ] Produce individual videos covering those specific topics, for instance one collating all the blockchain career advice that different people offered into a single video.
- [ ] Continue this to produce a series (or at least as much as is possible within the scope of an internship).
- [ ] Produce a .md / web page that links to videos and provides short bios of people interviewed.
- [ ] Supply that to @shannona for inclusion on the Blockchain Commons web pages.

If someone is more interested in directing/creating new content, this could also include:
- [ ] Add more interviews of blockchain luminaries to supplement these videos.

(But we'd want to make sure we had some final, publishable content at the end of the internship.)
