  • 600 Million GB of information/year → 36 Billion GB by 2009

  • 93% is digital

  • ~8 Billion public web pages already


information abundance!

economics of abundance

… A rabbit-rich world is a lettuce-poor world, and vice versa.

The obverse of a population problem is a scarcity problem, hence a resource-allocation problem. There is only so much lettuce to go around, and it will have to be allocated somehow among the rabbits …

Herbert Simon


economics of abundance

Similarly, in an information-rich world, the wealth of information means a dearth of something else: a scarcity of whatever it is that information consumes.

What information consumes is rather obvious; it consumes the attention of its recipients.

Hence a wealth of information creates a poverty of attention, and a need to allocate efficiently among the overabundance of information sourcesthat might consume it.

Herbert Simon

Simple way to measure attention is time spent on something.


conserving attention

Aggregated blog sites…

RSS aggregators…

Recommendation systems (amazon.com)

Algorithmic Boost

Search engines…

Social bookmarking…

Social Boost


How are people using these technologies to augment their everyday information assimilation?


The SEIC model (Nonaka & Takeuchi)

Tacit knowledge becomes explicit by observing technology usage in the context of a task.

systems


people do more than just read

sharing

other

browsing

reading

annotating

correlations


small number of general, online tasks

staying up-to-date

e.g., looking at news, Flickr photos

monitoring specific topics

e.g., furniture on Craigslist, updates on the iPhone

specific searches

e.g., e-discovery, rugby, hotels

refinding old information

e.g., last year’s poster tips

social distribution and influence

e.g., sharing information with various communities


information diet conforms to

a personal long tail


long tail information diet


basic process of information assimilation


intention: saving for self


intention: self + others


intention: sharing with others


lowering system costs increases sharing

conclusions

Information assimilation is more than foraging,

also organizing and sharing

People use social and algorithmic tools

to reduce attention to take advantage

of information abundance


conclusions

transactional costs --

user participation ++

information

assimilation ++

attentional costs --

social filtering ++
