Beside Trulia, I have also found that more buyers are utilizing other tools to locate properties and agents such as Facebook, Twitter, ActiveRain, Blockstopper, Zillow, Redfin, etc. I have also gotten contacts through Linked In which I essentialy thought of as only a professional networking site but there are also buyers that utilize this and many other sites.
Hope this helps and good luck to you.
