Deep thinking for branded utilities
If you're working in the branded utilities space, there's a recent talk/presentation that you should become familiar with. From April's Web 2.0 Expo, it's called 'Polite, pertinent and... pretty: Designing for the new wave of personal informatics', and was put together by Matt Jones of Dopplr and Tom Coates of Yahoo! Brickhouse.
It's long, it's thoughtful, and I suspect that it will be very influential in the years to come.
