Home from ETech. It was a tremendous experience for me. The positive spirit of these pioneers and inventers is truly uplifting. I met great people, and learned so much. Now I'm back to work, trying to figure out what I can do to help.
I wish I had blogged more, but other, more experienced bloggers did an admirable job. And, many of the presenters put their presentations on the ETech site.
Someone at Joshua Schachter's GeoURL talk at ETCon mentioned the Degree Confluence Project. The idea is to visit every integer lat-long intersection on earth, take pictures, and post them. I love this!
"Life Goes Mobile" is a motivating vision at Nokia. How to free our lives from "the screen"?
* Interacting with the world, not the screen. More immersive. Pervasive networks. Touching, tangible interactions. E.g., touch mobile phone to an object, get info on it (Like AURA!).
* Devices must adapt to work in the environment (e.g., various networks, context (home vs. work)).
* Simplicity of UI is paramount. Device must ALWAYS WORK.
Two approaches to designing new mobile devices: start with a PC and shrink it, or start with an existing mobile device and grow it.
He forsees the blending of various networks -- cellular WANs, hotspots, bluetooth. Devices need to support them all, rather than just one or two.
Strong belief in open standards (plug for OMA). Plugs Symbian and Series 60. Nods to Java. Mentions future support for Python and Perl on Series 60.
100 MM devices to ship with Series 60 and Java this year. Over 1500 existing S60 apps.

Marc is a research sociologist at Microsoft Research. Previous work included NetScan (UCLA), that studied Usenet. Now focused more on mobile devices.
He says, "I work for a small software company in Redmond, Washington, and I'm down here on a work release program."
Others who study the "social space"
How do these concepts differ from (online) Community, Groups, ...
Seminal works from Sociology:
Robert Axelrod, The Evolution of Cooperation
Elinor Ostrom, Governing the Commons -- The Evolution of Institutions for Collective Action
Erving Goffman, The Presentation of Self in Everyday Life
Edward T. Hall, The Hidden Dimension
Social Network Analysis
Edward Tufte, Visual Explanations & The Visual Display of Quantitative Information
Marc Smith (ed.), Communities in Cyberspace
Online aggregations resemble voluntary associations far more than groups:
* They are often larger than "groups"
* Their memberships are skewed to power law distributions
* Most people aren't very active
Virtual Schelling Points
* Sites of coordinated action
* Affordance for association
* Yphrum is Murphy backwards
* "Systems that shouldn't work sometimes do, or at least work fairly well."
The Value of Reputation on eBay: A Controlled Experiment
Ostrom's design principles for groups to organize and govern themselves:
1. Group boundaries are clearly defined
2. Rules governing the use of collective goods are well matched to loal needs and conditions
5. A system for monitoring members' be3havior exists; this monitoring is undertaken by the community members themselves.
6. A graduated system of sanctions is used
Goal: Plumbing for collective action
* Architecture and furniture for association
* Key tasks for participants in conversation in communities:
-- Discovery, Selection, Evaluation, Motivation
Marc's group studies Usenet.
* 240MM messages posted
* 8 MM unique authors
Netscan: Data mining Usenet and other conversation repositories
Treenet -- a visualization tool for activity within news groups across Usenet
Other visualizations of individual activities -- how many posts, how many threads, how many threads initiated, etc.
Explicit vs. Implicit Reputation Systems
Explicit: Ebay, Amazon
Implicit: Googel, Amazon, Blogdex, Technorati, Netscan
Mobiles Devices as the New Mouse
* Laminated reality
* Access to information about everyone, anywhere
nTag People Network
AURA: research project to link physical objects to onilne data, using barcodes (rather than RFIDs, since they're not there yet). Scan, Tap, Display! Find metadata online for real world objects. Link people to people through shared objects. E.g., in an art gallery, you scan the barcode with your handheld, and get online info about the art object you're looking at. Another example: product labels for packaged food products. Find out whether the food is GMO. Etc. Uses Resolution Services, essentially brokers for online information (e.g., UPCs, IPBNs, hosting for annotations for groups of friends, family, coworkers).
Make it work with cheaper digital cameras: vision based decoding is difficult.
Try it: Wifi Pocket Pc or Phone Edition phone, SDIO socket barcode reader
The latest Social Network toy here is Flickr from Ludicorp. It focuses on photo sharing, and IM/chat around the photo sharing experience. I met Stewart Butterfield, their president. System seems very robust under the hood. More on this tomorrow.
Median time from weblog post to live index: 7 minutes
Introduced text search last week (cheers)
Cosmos service searches for links in blogs. Search for www.amazon.com shows that most links are "deep" -- i.e., they refer to a specific product (esp. book). This demonstrates the value of Amazon's web services api... But also provides a real-time view of what products or books people are blogging about.
Top products discussed in the last 24 hours at: http://www.technorati.com/cosmos/products.html
In general, this lets us watch the spread of ideas, people, etc. across the net. For example, people at ETech are blogging in real time -- and embedding the links above -- and these are showing up in Cosmos searches in real time!
