I don't know what this means or what formats are preferable or why. I just want the max data and highest resolution so that nothing is left behind when folks want it in the future.

Apparently there are open-source archival things that can webscrape/snapshot pages. That doesn't seem too difficult, but what do I know. The tricky part (to me) is having it automatically add to meta-table-lists on wikis and posting this on SaidIt (or other forums like Corbett Report, etc) that it's been archived after actually archiving it all and sharing it on IPFS.
