INTRODUCTION
Technology-Mediated Communication
People communicate with each other not only to request
and share information and coordinate activities, but also
to establish and maintain social relationships [3,16].
Planning and carrying out the behavioral interactions
upon which relationships are built requires an investment
of time and energy that can be significant, and the
frequency and intensity of these exchanges predicts how
“close” a relationship is [2]. Berg and Clark [1] define
“closeness” between two people as the degree to which
their behaviors are interdependent, and asserts that they
make decisions about whether or not their relationship
will be close based on factors such as the perception of
the other person’s availability, responsiveness to past
actions, and concern for their needs.
