"Speed kills … except for real estate." –Anonymous
People are using Twitter to share their experiences. They are also using it for crowdsourcing: posing questions and problems to a group of people.
They are hoping for a quick and useful reply. They tweet (post on Twitter) for advice. They tweet for referrals. They tweet for real estate advice. Yes, they tweet that they are looking for homes … and Realtors. No kidding.
