Microsoft plans to give its MSN Spaces blog publishing and hosting service new social networking features, as well as support for the company\u2019s lightweight applications called Gadgets.The new social networking features are being tested by MSN Spaces users in Australia and the Netherlands, and are designed to foster user interaction, said Karin Muskopf, MSN product manager."We\u2019ve heard from our customers they want to be able to see who their friends are talking to, because they feel those people would have similar interests to theirs. They want to be connected to people who are like-minded," she said.She declined to comment specifically about social networking competitors, but News Corp.\u2019s MySpace has revolutionized this market with its eye-popping popularity. Beloved by teenagers and young adults, MySpace ranks second only to Yahoo in page views in the United States, and drew almost 5 percent of all website visits in March, ahead even of mighty Google, which drew little over 4 percent, according to Hitwise. MySpace currently has more than 73 million registered users worldwide, and adds about 250,000 new ones every day.MySpace\u2019s success hasn\u2019t gone unnoticed by large providers of online services such as Microsoft, AOL, Google and Yahoo. Google has an invitation-only social network called Orkut, and Yahoo has a blogging service called Yahoo 360. AOL recently launched AOL Pages, a social networking service tied to its AIM instant-messaging service.Ironically, MSN Spaces may also end up competing with Wallop, a start-up that is developing a social networking service with technology Microsoft spun off from its research unit. Wallop plans to launch its service this year.MSN Spaces, launched in December 2004, has always allowed users to link to other blogs on the network. But the plan now is to make this easier to do and more attractive, by letting users add a section to their blogs where they can build a gallery of "friends" who also have MSN Spaces blogs.While this functionality is now limited to a simple hyperlink, entries in this new gallery will contain much more information about the friends, even including notes and tags the user can add about them. The social networking features will also be integrated with Microsoft\u2019s instant-message service.The tests in Australia and the Netherlands have been going well, and Microsoft plans to extend this functionality to users in other countries in the coming months, Muskopf said.It makes sense for Microsoft to try to leverage the sizable MSN Spaces audience to go deeper into social networking. About 40 million people have set up MSN Spaces blogs, and the network receives about 120 million unique users per month, she said. Around 6 million photos are uploaded to the service each day for a total so far of about 2.5 billion.Meanwhile, MSN Spaces will also gain support for Microsoft\u2019s Gadgets, the lightweight applications introduced last year as a way to extend the functionality of larger desktop and Web-based applications. Microsoft provides a website where developers can find information on how to build these mini-applications. Muskopf declined to provide details on how Gadgets will be supported within MSN Spaces.-Juan Carlos Perez, IDG News ServiceThis article is posted on our Microsoft Informer page.\u00a0For more news on the Redmond, Wash.-based powerhouse, keep checking in.Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
