Twitter and the mortgage industry

We have been watching twitter and how mortgage professionals have been using the system. Seems like it is being used only to drive website traffic. We have our own twitter page http://www.twitter.com/privo and have about 460 people following us and are following a lot of mortgage professionals ourselves. Most of the people who have gotten in touch with us are those trying to pitch some "get rich quick" schemes or trying to drive traffic to their website.

Would like to know if anyone has some good experience utilizing twitter- particularly on the mortgage banking side. We are working on putting together a white paper on how mortgage banking/broking professionals can benefit from twitter.
