Wired has an article about a new service called Cellphedia, which it calls a wireless Wikipedia they call themselves the 1st Ubiquitous Social Encyclopedia!
Looking at the service it seems to have a few difference to the British based AQA that I have written about before. The service was part of a post grad course. Unlike the British service a users question is answered by other users who claim to have specialist knowledge in a specific site. As well as sending the reply to the person requesting info the response in posted on a website and the first person to respond is rewarded for doing so.
The most interesting vox pop is this:-
"Jimmy Wales, president of the Wikimedia Foundation and founder of Wikipedia, said he's seen Cellphedia but hasn't used the site. He said he thinks Cellphedia sounds like a great idea, and that Wikipedia is actually in talks with Nokia about creating a Wikipedia client on Nokia cell phones."
Now if one of the handset guys starts putting Peer-2-Peer based services such as this on a device then we could see something very interesting develop. I guess it depends on the price structure and who gets paid for what as to if the service is a success. But tghe plus side is that this is one of the interesting services to come out of America now that they are understanding SMS.
