This is a fascinating episode. Jason Scott works for the Internet Archive, personally hosts a large archive of historic BBS text files, and is an engaging interviewee (plus, he talks a lot :) )
If you’re interested in how archive.org works (including how they choose disks for their storage, how content is processed and managed, whether they keep spam, how many hours of “sermons” have been stored, etc), or what happens when you get sued for USD2,000,000,000, it’s well worth a listen.
