In any case, I still don't see that the specific blog is committing to anything, beyond the author's preference. And I'm still not sure I think that the 'blorb' and the 'gloricle' is a coherent division. Like, I would put prep in blorb, frankly, its more stuff that has been made up, part of the fiction. One thing we agree on, there's a fundamental difference between Low/No Myth Story Now and Pre-authored play.
That could be because I wasn't trying to explain or advocate blorbing, only to comment that neither No Myth nor Blorby play are objectively better than each other: when and how to canonize facts is simply a matter of preference. Since your point appears to be that Blorb, in your opinion, is merely "High Myth" narrativist play, presumably you would agree that both preferences are valid: No Myth and High Myth.
I don't want to derail this thread or argue about what "committing to anything" entails, but I
do enjoy blorb far more than No Myth play, so I'll just link
Blorb Principles and leave it at that unless someone starts a thread on that topic.
Edit: except for the below clarification.
However, I know of no use, within that general tradition, of anything resembling Story Now Zero Myth type play. It might be thought of as being related to theatrical improv, but I think that would be a pretty big stretch in the sense that they don't share techniques.
I think you're responding to the statement that '
I didn’t invent blorby play; both blorby and unblorby moments, or entire games, have been played in RPG since the seventies or earlier.'
I will point out that you're assuming that 'unblorby play' means 'Story Now Zero Myth', but it doesn't. See
Blorb Principles for additional criteria beyond No Myth, but for example anyone who disagrees with the statement "
A good prepper might think of things like theme, fairness, balance, things being evocative etc but once you start running, all those thoughts need to go out the window" is not blorbing. (And that's okay! Not everyone has to blorb. The point of the word is just to identify the playstyle, not to religiously advocate it.)
Does that help clarify in what sense non-blorby play has clearly existed since the 70s? Based on what I know of his personality, I doubt Gygax saw anything wrong with leaving on his "game designer" hat whenever he put on his DM hat and sat down with players. I suspect he felt quite free to improvise theme, fairness, balance, etc. right in the middle of a game session. Ergo, Gygax was probably non-blorby much or most of the time.
