I've never used any formal writeups like that. I have definitely incorporated other people's stories about how they ran various modules though. It is why I think certain modules end up with a higher reputation than is strictly warranted by their text; the module is what is written in the text, plus 40 years of DMs talking and writing about how they interpreted/modified/expanded that text, much of which is now part of the collective (DM) unconscious.
On reflection, I probably have picked out one or two items out of that sort of post, but I find the bulk of the material one of (a) too campaign specific, (b) not conducive to my style, or (c) not really an improvement. I find the sorts of conversations we have in this forum to be generally more interesting, and more useful.
Like, imagine if we took a classic module that doesn't actually get a lot of write-ups, like D1, and hashed out various ways of approaching it, or handling movement through the tunnels at the table. Or really any module that someone was thinking of running. I could totally get into "module club".
