It's always worth thinking about who the audience / userbase of your UI is, and whether they'd benefit from an expert user interface [1] or not.

Sometimes, they would (e.g. the "users paid more than the programmers" rule of thumb, but also: various technical disciplines, most anything used for professional-grade work). Sometimes, they wouldn't - or perhaps some would and some wouldn't (so perhaps you're looking for a simple base UI with some accelerators [2]).

IMHO the issue is that many products fall into this last camp - where a well-designed simple UI is called for, but also accelerators could greatly help a small but important subset of power users - but we treat the power users as though they don't exist.
