Job portal?

I am looking to create a job site that is different and unique from others out there? Is there something that you people miss when using a job site? What things you would like to have in a jobsite to make it more useful to you. What kind of searches would you like to perform for the results that you seek? Any specific regions that you think need a good job advertising board desperately?
