People need to know that social media sites don't sell real estate before they get overly excited and start setting up profiles on Facebook and LinkedIn, and open accounts on Flickr, join Twitter and start a blog.
None of those services sell real estate. It is really too bad because so many good agents are spending their time on the Internet these days. I can give examples of how all of these nifty Web 2.0 sites have failed me. Recently I had a prospective buyer -- we will call her "Mary" -- who had been lurking on my blog. She contacted me one day and told me that she really wants to buy a house.
