Chapter 7. Reduction > Reduction in pervasive information architecture

Reduction in pervasive information architecture
Anderson's economy of niches does not presuppose an infinite global availability of choices for all, but a wider range of options in specific fields—the niches—in which individuals could not previously have them as these were isolated from the larger mainstream markets.
(Dini 2006).
It's more choices then, but only in the niche or domain we are interested in. If we consider Anderson's long tail from the perspective of a specific user, his model actually implies a reduction in the range of choices: from all those that are theoretically available to only those that are of some interest. This could be the result of filtering mechanisms that allow discarding unnecessary items; for example, the way the Amazon Web site implements its systems of dynamic correlations: “Frequently bought together,” “Customers who bought this item also bought… ” “Look for similar items by… ” and so forth (Figure 7.9).
Fewer, selected choices at any given moment
