The AIGA has podcasts and presentation materials up for some of the speakers from the Design Conference (my full coverage here). Several of the main stage speeches are up, as well as backstage interviews with some of the participants. In particular, I would recommend:
- Audio of the main stage presentation and interview with Juan Enriquez.
- Audio of the main stage presentation by Bill Strickland on The Design of Leadership.
- Audio of the main stage presentation by Milton Glaser and Nicholas Negroponte.
- Audio of the main stage presentation by Murray Moss, although I'm not sure how well this one would work if you listened to it without the slides.
- The PDF of Stefan Sagmeister's presentation doesn't make too much sense without the audio, but the last 50 or so slides are worth checking out for the design candy.
These aren't just for designers; they're perfectly fine for non-designers as well. Here's the RSS file with all the resources...it should work well with your favorite podcasting software or newsreader. It's great that the AIGA is making these presentations freely available...you're getting a lot of the conference for free here. If I remember correctly, not even O'Reilly offers the presentations or podcasts for download after their events like Etech.
Update: Wrong again! IT Conversations has several podcasts from the last Etech conference. (thx tim)
