Agile and GTD

I know something about Agile methodologies for developing software, albeit at the 30,000 ft level appropriate to a Mere Suit.

I know a lot more about GTD, being a deep addict of many years’ standing.

It seems to me they have something in common.

Weekly reviews = ends of sprints

Projects/folders/multi-step tasks = stories

etc.

Any thoughts from the Agile-oisie?
