As historians, what would you want today's populations to record in diaries, blogs/vlogs, etc. to better assist historians of the future?

The title explains it but what are things, as historians, you wish others would do to "pass on the torch" of knowledge to the future generations?

I would imagine that digital photos and videos would be incredible but wonder if the formats will be compatible 500 years from now.

I am curious and hope this is not an improper question for this great sub. Thanks!

EDIT:

Also, I would imagine that each person has a unique perspective to contribute (military veteran, homosexual single-parents in Idaho, artist in Berlin, etc.). How would each of these individuals best capture their experiences for your future counterparts to dissect and further historical knowledge?

Everyday events not related to big news stories, but more local and personal. The sources could include a digital "diary," social media, video, or old-fashioned paper.
