I was trying to link to a gmane article in that answer, but none of the:

message message message message
A lot of the Unix history is documented on usenet (which predates the world wide web), and gmane which contains archives of a lot of Unix-related mailing lists (including the POSIX working group's whose earlier posts can only be found publicly there) is nowadays only available over NNTP.
Usenet is or at least was core to the Unix culture. Unix.SE is to some extent a bit of the continuation of
comp.os.linux.*. I recognise a few names from there here.
It would be useful to allow those links at least on the unix.SE site.
