Get ready for mobile social networks

But questions remain over how to make it profitable for companies, secure for users

Weide said he had talked to executives at two major social networking companies, which he would not identify, who expressed concerns over how they would raise revenue and how much revenue wireless carriers would want to share. In addition to sharing revenues, social network providers have to figure out how much of a customer's personal information to share with carriers, and vice versa.

Another panel discussion included five industry officials who cast doubt on whether mobile social networks can successfully be supported with revenues from advertising seen by end users. If advertising doesn't support the concept, then carriers and social network providers will probably have to rely on subscription fees, the panel members said. Questions still remain over how much a user would be willing to pay for a subscription, since that fee might be on top of the cost of a user's unlimited monthly data plan.

"Advertising is challenged" as a way to support mobile social networking, said Paul Rehrig, vice president of business development for Warner Music Group. However, he said that many companies, including those selling music, are likely to have more success selling certain content to mobile device users than has been sold to desktop computer users.

With music, there is great potential for sharing tunes and reviews through mobile social networks, said Mari Joller, director of new services for Virgin Mobile. She said there is great potential for mobile social networking, given the way young wireless users are already flocking to text messaging and relying on social networks from their desktops.

For that group, "we've found that people are terrified of being out of touch," which means a mobile social connection will be ideal, Joller said.

Still, Joller and others said carriers and social networking sites will have to be vigilant to protect privacy and safety, especially of minors who could be the subject of stalkers or who don't want to communicate their location to a former friend. Controls can be built in and should be, she said.

"We have to have controls that say 'Are you sure you want to share your location,' " Joller said. "We have real life examples of somebody stalking" through social networks. "It's going to take education with growth in the market ... With the youth demographic, there could be some scary situations on our hands."

Weide said mobile social networks "will be a non-starter" if all the parties don't put in plenty of privacy and security controls upfront, especially for young users.

Mobile social networking could lead to many uses that are only now being imagined, analysts said.

Benjamin Mosse, director of mobile products at the Associated Press, said groups of friends could share news stories and offer comments within their group, instead of posting comments directly to a story. And down the road, he said the AP itself could use GPS technology to track what stories are being read in certain cities, zip codes or buildings.

"I would like to know what the editors inside of AP are reading," he said. The AP last week announced it is making content from its 700 news organization members available on Research in Motion BlackBerry devices, and announced this summer it is offering the same service via iPhone.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
