Web 2.0 - Maximizing Interactivity

In all the myriad definitions of "Web 2.0", one characteristic stands out as its basic essence: a high level of interactivity. This idea must be defined further, but at its simplest, Web 2.0 webpages minimize user frustration and maximize site "stickyness".

Web 2.0 webpages are borne out of new technology that allows for interaction without page refreshes. This has a significant effect on user experience, as it speeds up navigation significantly and provides greater feedback to the user. As the user becomes accustomed to such interaction, an even more powerful effect emerges: The user becomes less fearful of interacting with the page because he/she knows what to expect, and doesn't worry about losing their place, or having to wait for another page to load.

It is only in retrospect, however, that the impact of this change can be fully appreciated. One remembers the feeling of fear and trepidation that would accompany clicking a link on an unfamiliar webpage-- what would happen? Would the link work? Would it take 30 seconds to load only to not contain the information I need?

Nowadays, it is common to use webpages knowing full well that certain links are reliable, fast, and often do not require any page refresh. Users certain of what to expect from an action are more likely to perform that action. Bringing this certainty to the everyday user experience should be a prominent goal of web developers.
