Quite some time ago we wrote about Mosio, which leverages a distributed based of users to answer queries of all sorts. It's one of a number of "mobile answers" services, which include ChaCha, Texperts in the UK and AskMeNow (although this has moved away from the human-powered model).

Twitter is a service that I do not use, but others love it. However, Twitter (or Twitter plus Summize) could become a very useful mobile search engine (for recommendations) or real-time "mobile social DA." What I mean by social DA, as in directory assistance, is a distributed base of users who substitute for the function of directory assistance.

Rather than the self-indulgent string of "tweets" (I'm in the car, I'm now getting out of the car, I'm now opening the front door . . .) one could ask the community for local recommendations. Alternatively, if an engine like Summize could filter out the "noise" among the tweets it might create a very valuable database of content that could be accessed on the go.
