Perhaps some pehnomena, especially those related to computer interaction, is due to something that  could be called information hunger. Surfing the web for instance, which can certainly be a healthy thing in terms of education, may also be detrimental, but in either case it may be caused some internal mechanism that craves information. This may also lead to channel-surfing; for some reason, a flat pattern of knowldge lacking depth, across several plateaus, is more useful than a deep knowledge in a single thing.

Flow is used quite loosely in writings on game design, HIC and interaction design. Flow is not the greased gears of an interactive experience; flow is not the measured ease with which a user glides through a process. Unless of course one is using a definition of Flow that differs from the originator of the term and concept - M. Csikszentmihalyi.
