I've been recommending Getting Things Done—The Art of Stress-Free Productivity to friends, co-workers, and techie mailing lists [see my review]. The following are some of the conversations my recommendation engendered.
My reaction to Vicki's quick overview of the book - it sounded like a typical time management system.
Interesting to me, because, from the time-management systems I've seen before, the Time Management class I attended a decade ago, and David Allen's comments on other TM systems (scattered through the book) it's really quite different. Perhaps subtly different :-) but different nonetheless.
