Seth Godin talks about "things that are broken" in this video.
Seth wrote Purple Cow and Free Prize Inside (along with several other books). Both books have been floating around our office since Scott started reading them.
He is an entertaining speaker, but also has a lot of good gems for people thinking about building and marketing software/technology. Our industry doesn't seem to be his focus, but it always seems that software/technology always has the most room for improvements!
