Move.com is on the move with a shaking out of senior management and some all-star additions to staff.

Lorna Borenstein, an attorney formerly with Yahoo!, has been named President of Move, Inc. and will report to chief executive officer Mike Long. She will have full P&L responsibility and lead day-to-day business operations, engineering, marketing and product development of the company. Borenstein served as Yahoo! vice president, product for Yahoo!'s strategy on youth and education, global vice president and general manager of Yahoo! Personals and vice president, marketing of Yahoo! Search & Marketplace Group.

Allan Dalton, former president of Realtor.com, a division of Move.com, has stepped down to work on a top-secret enterprise for Move.com. Joining him will be David Lereah, former chief economist for the National Association of Realtors. The new enterprise is anticipated to serve consumers and real estate professionals. It is not known whether it will be a separate unit or folded into Realtor.com or another unit.

Stepping up to be president of Realtor.com is Errol Samuelson, former president of Top Producer, a productivity software division owned by Move.com. Samuelson is the first "tech guy" to be in the position.

"We hope to build upon the success of Realtor.com," says Samuelson, "provide new services, and continue a positive relationship with NAR and its members."

"I have a focus on technology and we intend to innovate more rapidly," continues Samuelson. "In the last five to six weeks we are making a difference with the new agent IDX website product. It's a beautiful product that provides rich deep community information, school information, demographics, income, weather, -- it's very rich. We have all the IDX listings where they are available with daily or weekly updates and mapping. Realtor.com was among the first to offer websites to agents, but if you look at this latest generation product, it's fantastic."

Adds Samuelson, "Another example is a gadget for Windows Vista. For anyone using the new Vista, you download the program, it sits on your desktop, and you type in 90210 and two beds, two baths. As you work, a small window shows you continuous slideshow of properties in the range of what you said you were looking for. It's a great consumer widget."

Realtor.com is reviving and enhancing push technology. The new website technology was built on top of technology that Samuelson and his team had been developing at Top Producer and configured it to build it on customers' websites. "I was heavily involved," says Samuelson. "My plan is to take a look at how we can take current and emerging technologies and provide better utility."

Rather than focus on the politics of Move.com and Realtor.com, the company appears to be changing direction to compete on the strengths of its technologies and market advantage.

According to independent third-party, Media Metrix, Realtor.com had over 6 million Unique Users in March (6,007,000). (Editor's note: an individual is counted as a “Unique User” only once in a given month, even if he or she visits the site multiple times).

Realtor was the No. 1 site in the real estate category with a commanding lead over the No. 2 spot (MSN with 4.15 million Unique Users). Incidentally, MSN also features Realtor.com content.

Traffic on real estate sites tends to be seasonal. With the spring market in full swing, traffic on Realtor.com grew from February to March by 20 percent. What makes this impressive is that this outpaces the real estate category in general, which saw traffic growth of only 13 percent between February and March.

Another important metric is "time on site" because it shows engagement. The average minutes of use for users on Realtor.com was 13.4 in March (No. 2 in the category, MSN, had an average minutes per visitor of 1.7 minutes.) Consumers spent 228 million (!) minutes on Realtor.com during the month of March.

This is 380 percent higher than the next closest website.
