Abstract
Social network site usage has grown to be a worldwide trend. These sites facilitate online contact between individuals having similar concerns. The speedy and extensive usage of such sites has affirmed their perception and positioning in the minds of users. This research adds to our consideration by empirically exploring determinants affecting users' acceptance of such sites. A HUMP model has been introduced to evaluate the effect of hedonic (perceived playfulness), utilitarian (perceived usefulness) e-mavenism, polychronicity, and perceived ease of use on the intention to use and thus actual use of social networking sites. The causal modeling technique is used to study the outline of associations amid the projected model constructs and to analytically evaluate the research propositions. All the conjectured factors possess a considerable unswerving sway on the intention to use, with e-mavenism and polychronicity, the robust indicators.
