Risks of Ajax on the Public Web

Category: Usability

Over at AjaxInfo, Alexei White is discussing the risks of Ajax on the public web. The second of three postings looks at several cultural risks:

  1. Heterogenous culture and expectations.
  2. Users are not very trainable.
  3. Short attention span.

A few of the solutions include:

  1. Do affordance testing.
  2. Keep it lightweight.
  3. Ajax as value-added functionality.
  4. Liberal use of visual cues & affordances.

These are timely points, as it seems likely mainstream websites will be introducing Ajax features over the next tweleve months, e.g. Yahoo! Mail. Many of the risks are magnified when Ajax is used on the public web as opposed to internal systems. At the same time, everyday users on the public web also have more to gain from rich interaction done right.
