So I don't know how much use it'd be for anyone else.

Well, maybe you're doing a sort of inverse of generalizing from one example in that you assume that your process wouldn't be of use to anyone else, when in fact, it might be useful? :-)

Your Seven Shiny Stories are also very specific examples that theoretically apply to that one person only but can serve to highlight more general principles.

Going for the meta article with "this is how you find those techniques" with an example added of "this is how I found this" might be the best though, similarly to how the Sequence/Seven Shiny Stories work now.
