Positives

• Excellent presentation skills -- intonation, humor, style.
• Excellent content; while I knew most of the concrete things mentioned in the slides, the way David tied ideas together and distilled them at the end into succinct recommendations.

Room for Improvement

• Not much! I would be very interested in seeing if David could evolve this talk into a secondary talk about "whence to use Mocks, Stubs and other Charlatans/Doubles". :-)

I liked the presentation, and the simplification of testing approaches, but kept thinking that I already knew a lot of it.

It might be that for this crowd we might have needed a different angle, maybe a common problem, or something that we all felt we needed. (I think that's a challenge for any testing talk, as lots of people feel like they don't NEED any things else)
