Today Thomas Vander Wal appears in Under the Radar: That cloud kinda looks like you! in an interview with Scott Hirsch who is a partner at MIG5. The interview focusses on digital identity, which is integral to the Personal InfoCloud and interacting with other people and services in the digital world. Increasingly it seems digital identity is tethered to physical world identity for access to buildings, accessing our computers, medical services, etc. This has some problems around privacy that must be addressed and there must be trust in the services that interact with out digital identity.
