Doing my standard breadth-first-search of people's blogs (omitting links of little interest), I ran across the Simplessity blog (via Nadyne via Brian Johnson). The particular article linked from the title is about a presentation by Barry Schwartz about how as the number of choices goes to infinity, the productivity (of maximizers at least) goes up, but happiness (in general) goes down. Facinating. This probably explains why people end up being paralysed when faced with the number of options our products support (assuming they actually are aware of them). ("How best to format this document? Oh, crap, that was the wrong way." Even if it was the right way.)
I really like the idea of Libertarian Paternalism.
