A Survey:
● Brief view of existing systems
● Design implications
from studies of information organization systems
● Future work

Design implications
Visibility (and reminding)
Integration with existing work-flow
Co-Adoption (affordance for people who work as a group to adopt the
system)
Scalability (with respect to the type or amount of information that the
user wants to process)
Return on Investment

Future work
Associate information scents with resources indicating:
1. The cost of foraging a resource
URLs, for example
2. The chances that it will be eventually used as intended
Bookmarks, for example
based on your history with other pieces of similar information
based on the information's history with other similar people
Prevent us from becoming information gluttons !

Spatial memory
Clark's nutcracker : buries 30k seeds across an area of 100 sq.miles places a stone on top of the stash recovers 70% of the nuts buried under several feet
of snow 278+ days
But human spatial memory is limited to around 10 objects and suitable only for short-term
