The idea of a distributed network of non-professional "responders" to a mobile question or search is one logical evolution of DA -- the original form of mobile search. In the past we informally labeled this concept "social DA." It's the marriage of search and social networking in a mobile context.

Mosio has tried to develop that model; ChaCha is working with a version of that model and, in the UK, so is the paid service Texperts. (Twitter may eventually develop this as well.)

Similar in many respects to ChaCha, Texperts uses a distributed group of individuals who must pass basic testing requirements. They're paid, as are ChaCha's guides. But unlike ChaCha, users pay for the Texperts service -- like traditional DA.

DA purveyor KGB this morning announced that it had acquired the UK based service: 

Texperts will deepen kgb's market strength and service capability for mobile text services. The success of both companies demonstrates that consumers have a growing need for the instant availability of simple, accurate and hassle-free delivery of information on their mobile phone. The acquisition will also enhance kgb's ability to build on the initial success of the company's text advertising program (www.118118advertising.com), launched in 2007 in the U.K., which enables advertisers to reach consumers via the medium of mobile text, a highly effective and cost efficient alternative to more traditional mass media.

It's not immediately clear whether the existing Texperts model will be retained (I'm assuming it will). But it's a fascinating thing to watch KGB (formerly DA wholesaler InfoNXX) evolve from a traditional DA provider to carriers to a consumer-focused, mobile search platform with ad support.
