While attracting attention is one of the prime goals of content providers, the conversion of that attention into revenue is by no means obvious. Given that most users expect to consume web content for free, a provider with an established audience faces a dilemma. Since the introduction of advertisements or subscription fees will be construed by users as an inconvenience which may lead them to stop using the site, what should the provider do in order to maximize revenues? We address this question through the lens of adaptation theory, which states that even though a change affects a person's utility initially, as time goes on people tend to adapt and become less aware of past changes. We establish that if the likelihood of continuing to attend to the provider after an increase in inconvenience is log-concave in the magnitude of the increase, then the provider faces a tradeoff between achieving a higher revenue per user sooner and maximizing the number of users in the long term. On the other hand, if the likelihood of continuing to attend to the provider after an increase in inconvenience is log-convex, then it is always optimal for the provider to perform the increase in one step. Our formulation also provides a natural account of the penny gap phenomenon, which states that decisions about free content and products signifficantly differ from those involving strictly positive prices in that the benefits associated with free content are perceived to be higher than those with even minimal cost.

HPL-2010-96 Enabling Genuine Eye Contact and Accurate Gaze in Remote Collaboration - Tan, Kar-Han; Robinson, Ian N.; Culbertson, Bruce; Apostolopoulos, John
Keyword(s): eye contact, gaze awareness, remote collaboration, natural interaction, immersive experiences
Abstract: Conventional telepresence systems allow remote users to see one another and interact with shared media and documents, but users cannot make eye contact, and gaze awareness with respect to shared media and documents is lost. In this paper we describe a remote collaboration system based on a see-throu ...

A variety of social networks feature a directed attention or "follower" network. In this paper, we compare several methods of recommending new people for users to follow. We analyzed structural patterns in a directed social network to evaluate the likelihood that they will predict a future connection, and use these observations to inform an intervention experiment where we offer users of this network new people to connect to. This paper compares a variety of features for recommending users and presents design implications for social networking services. Certain types of structural closures significantly outperform recommendations based on traditional collaborative filtering, behavioral, and similarity features. We find that sharing an audience with someone is a surprisingly compelling reason to follow them, and that similarity is much less persuasive. We also find evidence that organic network growth is very different from how users behave when they are prompted to connect to new people.
