BuzzD: Part Cityguide, Part Social Network

New mobile "city guide" and social network BuzzD has launched. The text-messaging based system is aimed squarely at a youth audience. It combines elements of local search and social networking.

The site also seems to be offering a technology back end that turns more traditional publishers into local mobile search sites and social networks.

The combination of local search on mobile devices, with one-to-many social networking elements could become a kind of "killer app" for mobile. There will be many companies eventually in this segment, trying to combine community and local search -- for example, Mosio and Whrrl, among others, as well as more traditional desktop companies, such as Yelp.

Here's some additional information from RCR Wireless News.

With its acquisition of Ingenio, including the Keen part of the business (minus the adult content), there's an interesting opportunity for YellowPages.com to create a new type of mobile Q&A or distributed directory assistance style business along the lines of AQA or Texperts.
