If you want a look at one possible future for the real estate world, read job jacking and replace every instance of job jacking with listing jacking and replace every job company with your favorite web-based real estate search companies. Sure, real estate isn’t quite so spread out, but it’s getting there.
I think it’s a silly complaint. People post jobs so they can find applicants and people list houses so they can find buyers. Most limits on where the jobs or houses are displayed are not in the interest of the lister.
