Take a good look at The Loop, it has all the characteristics of a job board, but it also embraced the ideals of social networking by allowing users to connect and collaborate. In fact, it is promoting itself as a networking site for the creative industry.
What doomsayers fail to recognize is the ability of job boards (or the business model) to evolve with the times. Be prepared to see more blending of the traditional with the new.
SMH did a piece on The Loop (Pip Jamieson and Matt Fayle are Co Founders).
