If you have an interesting lecturer at university or even school, record their lectures and upload them. The fact that you can access lectures by a top Heidegger scholar, Hubert Dreyfus, on YouTube is down to some enterprising student recording & uploading them.
We also, for the first time in history, have the ability to record the commonsense advice your grandmother, uncle, or other elder may give you. Record this too! Record their stories! More for the historical record, and a means to minimise the ideological manipulation of history.
