In the Git and mailing list history, we've got lots of references like <http://permalink.gmane.org/gmane.emacs.orgmode/112052>. Those Gmane http links aren't so useful now, though you can still use that information to access the message by doing things such as
$ w3m -m nntp://news.gmane.io/gmane.emacs.orgmode/112052 (Offhand I don't know how to do the same in Gnus, despite it being my primary method for following things over nntp.) Anyway, for the public-inbox archives at <https://yhetil.org/orgmode>, I've recently generated Gmane ID to Message-ID mappings and hooked them up to public-inbox's altid feature. The end result is that you can now use the "gmane:" prefix to search by the Gmane ID: https://yhetil.org/orgmode/?q=gmane%3A112052
