Related, I noticed there is a sort of continuum in analysis via technical means, from "boredom" to "mystery", like:
movement > momentum > mean reversion > moving averages > support/resistance > fibonacci levels > historical mega- or meta-periodicities > novel periodic models > coincidence of observable movements > numerological indicators > coincidence of inequitable movements with equitable > karmic models > etc.
Not that one of these is "better" or that the sequence follows any kind of evolution, but rather the emergence of the continuum itself is an interesting phenomenon in a variety of disciplines, from meteorology to earth sciences to equities trading.
It'd be interesting to see a community that really explores this topic in general terms, with discussions forming around specific areas within. I wonder if anything like that already exists?
