It seems these days that the consumer is being attributed success to every aspect of marketing. While that is really just laziness, there are a few projects that wouldn't be possible without the work of zealots. DXInteractive has done an incredible amount of research to create a visual encyclopedia of skateboarding tricks. This interactive reference has tricks and terminology, that has been verified by skaters themselves, much like wikipedia. Skateboarding terminology is often subject to localism and tricks can actually have two different names despite accomplishing the same result. This open source experience has become one of the defacto guides for skaters through its open-sourceness along with its meticulous trick list. Great example of consumer created content, but i wouldn't give em the bank yet.
