Sounds like a contradictio in adjecto or contradiction in terms? Perhaps not. See the following link to the Google Group The Efficient Academic, which could be more active for my tastes.
One of the relatively recent entries I liked most was a short review of Circus Ponies Notebook for the Mac. See Mini Review. It also contains an intriguing reference to Ulysses, a "predecessor" of Scrivener. Another entry I found interesting concerned Robert Boice's Professors as Writers, which recommends daily short writing periods over longer periods once or twice a week.
