GPS-enabled mobile-socializing trend

Interesting to get the Australian perspective on what looks to be a worldwide trend: "Experts say the 'killer application' for mobile social networking - the ability to access social networks such as Facebook and Bebo on mobile phones - will be the ability to use the global positioning software now found in phones to help cyber-buddies meet at-real life locations," Australian IT reports. The tech news site says, though phone-based social networking is very new in Oz, it's "growing at such a rapid rate it has become a key driver of mobile Internet use in the past six months." It cites a mobile marketing executive as saying he spends more than half his cellphone time on social-networking sites, which he thinks will become commonplace for everyone within two years. MySpace says that, worldwide, it "attracts 1.9 million mobile users a day." Meanwhile, Japan is already there. In that country, "the mobile Web is [already] bigger than the PC Web," the Washington Post reports, but home-grown companies may do better in the mobile space than US-based ones, as has been the case with Japanese social networking on the Web.
