so lots of people think social networks are worth lots of money
and lots of people think mobile phones are worth lots of money
what can you do with a mobile phone in terms of social networks
1. obvious (I wrote this ages ago) is run a browser (flock) on yr smart phone and go to a social net site
2. obvious (everyone wrote this a zillion years ago) - run a location service and map people's geo-relationships to each other or to locations or both (see MIT reality mining, Intel's project doing location service using just about anything a few years back etc etc)
3. do pocket switch net and decentralised link discovery (non obvious, but we did it in pre-haggle project work about 4-5 years back) and build temporal graph in a distributed way, then use it for
i) establishing relationships (co-lo duration and frenquency above some threshold)
ii) to actualyl forward info (person to person or pub/sub, via percolation, gossip, epidemic, but filterered by relevance (e.g. interest/tags), and by trust/tribal/dunbar/closeness etc) to get efficient delivery and focus...
This is gonna be the topic for the Million People project, and is discovery (not invention) and therefore not patentable:)
clever algorithms to make it work relaibly are more interesting though...
