Posts should have fixed identity
Adam Sacarny floods the Planet : time and past that we start designing weblog software so that a post has immutable identity fixed at the moment it’s first saved, not mutable identity generated when a feed is rebuilt.
Hear, hear.
WordPress already does this, since 1.5.
Ah, so the ”as you can tell by every post becoming new again, I’ve updated to WP 1.5” thing is the one last time, as they change URLs or change from whatever sort of guid they had before to an actual unchanging guid? Cool, I’ll take that tradeoff :)
It’s actually a permanent GUID that is stored in the DB and is independent of anything else. We also import them now from RSS, so if you import from RSS GUIDs are preserved.
