This post by Michael Leddy advocates something called "Amish Computing," a phrase that seems to come from Paul Ford. It's related to the Lo-Fi Manifesto and Living in Text Files.
I have some sympathies for this approach, but I am more like the Amish who own a car (but remove all the chrome and other adornments). That's another way of saying that I like the wiki-approach which is very much like the pure text approach with a database and structural make-up (and all the affordances of these conveniences).
