Mark Pincus has put forth an hypothesis  that in the future , information will revolve around people rather than pages. A quick summary of the main points:

1.Web will be categorized based on people, their profile, interests, affiliations, needs.
2. Customer will feel the lock in they face with the current email service providers (they can’t move their emails across SPs). Ultimately open exchange of profiles and people info will happen across net.
3.Network acts as one database caters to a whole set of needs, thus becoming a market place.
4.Big players realize that they are better off aggregating and syndicating than trying to stand alone defending their franchises and competing with the overall network.

For the above hypothesis to come true,one needs to consider the following aspects :
1. Need of Open Standards that will facilitate the movement towards peopleweb. RSS standard is a classic example for the nascent blogging business
2. Businesses realizing the importance of adding value to the customer by adopting the open standards.(Having API’s released to all, etc)
3. Since the information about the people is culled from the network, the authenticity of the info becomes prominent . Who vouches for the authenticity of the info?
4. Considering that commerce is an essential building block of peopleweb, Identity theft needs to be abated for peopleweb to move forward.

All 4 aspects will play a crucial role in deciding whether peopleweb see the light of the day.
