It was a week ago Sunday when DJ Waldow decided to start an experiment from his laptop computer. And it began with a simple question:

"Is it possible to leverage power of Twitter to sell our house," he typed.

Call it "Tweal Estate" if you want. Call it an extra outlet for selling in a down economy. But Waldow is hoping the 1,150 people who follow him on the social networking site will help him and his wife sell their home near central Durham.

"When I first started talking about it on Sunday, I had 108 different clicks on the site," Waldow said. "When I Tweet something out -- it could potentially be seen by a thousand people following me. But when somebody else re-Tweets it -- it can be seen by a thousand people following them. So it spreads pretty quickly."

By week's end, more than 400 people had clicked on the link he's "Tweeting" through the real estate site Trulia. Some of his followers are doing him a favor by reposting his messages for their friends.

"You can see all the other people re-Tweeting it," he pointed out on his computer. "This is somebody who lives in Chapel Hill. This is a guy in Durham."

"Some of these people on here -- no idea who they are."

One thing that could be fueling Waldow's experiment: he's offering $250 for the person who actually finds a buyer for the house.

"Very random connection -- somebody who sent it out to a friend of hers ... I didn't know her but she lives in Rochester, New York, my hometown," he said. "She has friends who are going to graduate school at Duke starting this summer and they're going to be in Durham this weekend. They actually talked about potentially renting the house."

Even so, when he signed up for the Internet phenomenon about a year ago, he wasn't completely sold on it.

"My original fear of it was that it was going to be a lot of things online -- it could potentially be a time-suck," he said. "I was really slow to adopt it at first, but once I did, I really got into it."

"It's incredible the number of people you meet."

Waldow and his wife are moving to Salt Lake City, Utah. She's in her residency as a doctor. He works in marketing for a software firm.
