Why are so many things broken?

Why are so many things broken? In this entertaining talk - one of the favorites of Gel 2006 - Seth Godin gives a tour of things poorly designed, the reasons why they are that way, and how to fix them

One of his examples is about parking your bicycle, which is so true! Also, who is designing those cycle paths here in Perth? I am pretty sure it's someone who never has cycled a day of his life! As you can't make 90 degree turns to go on or off a cycle path! And try to cycle in the maze of the city cycle paths, half of them block after a few hundred meters and you can't go any further, without any notice, so only thing left is to turn back and take another path... There are heaps of examples... unfortunately...
