As I think of it more, rather than B2B or B2C the biggest buzzwords of the dot com 1.0 era , it is the consumer 2 consumer(C2C) kind of models which are making real value. The internet is like one giant switchboard which connects one end point to another end point at significantly low cost. Examples of these are eBay, Craiglist, Flickr, del.ic.ous, buzzant, Napster, Kaazaaa.
They are all platforms which enable a consumer 2 consumer transaction take place. When a consumer has something to offer to another consumers he is basically acting as a producer. So s/he should be rather termed ‘prosumer'(= producer + consumer).
The above examples P2P [ Prosumer 2 Prosumer] models are going to be rampant in dot com 2.0. Looks like P2P state of the society is going to be the one with least entropy and world it inching towards that. Check out these ideas server decentralization and viral networking .
