Post-launch ideas

If we decided to do any of these they can be broken into their own issue:

- Use the [China Video Block](https://github.com/cncf/china-video-block) to show accessible versions of presentations to users inside of China
- Allow for multiple languages of a given presentation
- Tag CNCF "official" or "featured" presentations to make it easy to find key presentations
- Have a tag or something to show which presentations contain a PPTX or Google Slides resource which could then be re-used or re-purposed for other presentations
- Add back button on single presentation pages to go back to full list

And here are some other ideas that came out of the meeting with Ambassadors:
- would be nice to display video duration to support “I have 10 minutes to watch something”
