Information Foraging

The June 30 Alertbox goes into a little bit of detail on information foraging. People act like hunting animals in their quest for online survival.

Besides the popular aspect of scent, it also talks about how people choose what to eat (select sites) and when they decide to hunt new patches (go to other sites).

It all boils down to a bunch of internal cost-benefit analyses. Your information architecture can steer people to deciding that your site is not worth the hassle. Or the IA can make it clear what to expect from the site and how to get it.
