Over the past four days I have volunteered to a) join groups in order to archive them, and b) run instances of Warrior, the ArchiveTeam download client. I never used Yahoo Groups, but watching the group names fly by I have been struck by the variety and earnestness of the communities it contained. Too bad for Verizon that they can't find PR benefit in cooperating with archivists, or even a possible business opportunity in preserving this content (AI training? must be some use for the dataset).
