I'll return Pete's serve one more time here. Today he talks about the 3 P's of personal social publishing. He offer's the following:

1. Personal
2. Professional
3. Public

I'm going to take another stab at it. Here's what I suggest:

1. Personified -- To encompass what Pete included with both "Personal" and "Professional," I feel this is more inclusive and flexible. We present outward appearances to different people all the time (family, friends, close work colleagues, work acquaintances, fellow hobbyists, neighbors). These are our personas and we use them to present different appearances in social publishing.

2. Proximal -- Looking forward, as devices increasingly become portable and embedded in the world around us, technology's proximity to us will become more important. This leads to location-aware technology and spatially tagged information. That information can be both the inbound (that which we consume) and outbound (that which we create).

3. Pertinent--This requires a little intelligence on the part of information and technology. The information should be somewhat autonomous and contextually pertinent to our situation. That means that the appropriate media (or metadata) that we consume or create automatically situates itself within the right context.

(Yes, I acknowledge that sticking with P's makes some of these word choices a bit of a stretch, but just focus on the ideas.)

These suggestions add an additional level of complexity to identity management, and I'm not sure that Google, Yahoo!, or Microsoft can accomplish this alone. I think it will manifest itself in an ecosystem of services, device makers, and information brokers--in addition to all of us contributing and direction the information based on our needs.
