I've been thinking about trust for many years.

We have centralized trust assertions from people like verisign and
other CAs.  Perhaps the OIDF is going to get into centralized
whitelisting too.

A more interesting approach is the decentralize architecture.  Note:
there's a difference between centralization and specialization.

The paper I like best is :

Agents, Evolutionary Games, and Social Networks"

I've been thinking lately about trying to form an abstraction
framework that could include the following 4 web of trusts:

http://trustmap.org/
http://bitcoin-otc.com/trust.php
http://www.gswot.org/
http://xmlns.com/wot/0.1/

Would love to know if there are any other relatively "open" trust
systems out there.

However, websites generally limit the choices available to users in order to persuade the user to login using a high value account with data and services (name, verified email address, social sharing, profile, Likes, etc).

Account Chooser and Mozilla's BrowserID are both relatively email-address centric because verified email address seems to be the bare minimum that sites need to to get in order to justify accepting a 3rd party login relative to just registering a local account.
