… 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 …
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.
Simple way to measure attention is time spent on something.

e.g., furniture on Craigslist, updates on the iPhone
e.g., e-discovery, rugby, hotels
refinding old information
e.g., last year’s poster tips

e.g., sharing information with various communities

Information assimilation is more than foraging,
also organizing and sharing

to reduce attention to take advantage
