Weblog Success: Exploring the Role of Technology
Helen S. Du and Christian Wagner

Weblogs have recently gained considerable media attention. Leading weblog sites are already attracting millions of visitors. Yet, success in the highly competitive world of weblogs is not easily achieved. This study seeks to explore weblog success from a technology perspective, i.e. from the impact of weblog-building technology (or blogging tool). Based on an examination of 126 highly successful weblogs tracked over a period of 3 months, we categorized weblogs in terms of popularity rank and growth, and evaluated the relationship between weblog success (in terms of popularity) and technology use. Our analysis indicates that weblog success is associated with the type of blogging tool used. We argue that technology characteristics affect the presentation and organization of weblog content, as well as the social interaction between bloggers, and in turn, affect weblog success or popularity improvement. Based on this analysis, we propose a techno-social success model for weblogs. This model postulates that a weblog's success is mainly associated with its ability to provide value for its users and readers at the content, the technology, and the social levels.

The Effects of Post-Adoption Beliefs on the Expectation-Confirmation Model for Information Technology Continuance
James Y.L. Thong, Se-Joon Hong and Kar Yan Tam

The expectation-confirmation model (ECM) of IT continuance is a model for investigating continued information technology (IT) usage behavior. This paper reports on a study that attempts to expand the set of post-adoption beliefs in the ECM, in order to extend the application of the ECM beyond an instrumental focus. The expanded ECM, incorporating the post-adoption beliefs of perceived usefulness, perceived enjoyment and perceived ease of use, was empirically validated with data collected from an on-line survey of 811 existing users of mobile Internet services. The data analysis showed that the expanded ECM has good explanatory power (R2=57.6% of continued IT usage intention and R2=67.8% of satisfaction), with all paths supported. Hence, the expanded ECM can provide supplementary information that is relevant for understanding continued IT usage. The significant effects of post-adoption perceived ease of use and perceived enjoyment signify that the nature of the IT can be an important boundary condition in understanding the continued IT usage behavior. At a practical level, the expanded ECM presents IT product/service providers with deeper insights into how to address IT users’ satisfaction and continued patronage.


Studying information seeking on the non-English Web: An experiment on a Spanish business Web portal
Wingyan Chung

The Internet is estimated to grow significantly as access to Web content in some non-English languages continues to increase. However, prior research in human–computer interaction (HCI) has implicitly assumed the primary language used on the Web to be English. This assumption is not true for many non-English-speaking regions where rapidly growing on-line populations access the Web in their native languages. For example, Latin America, where the majority of people speak Spanish, will have the fastest growing population in coming decades. However, existing Spanish search engines lack search, browse, and analysis capabilities. The research reported here studied human information seeking on the non-English Web. In it we developed a Spanish business Web portal that supports searching, browsing, summarization, categorization, and visualization of Spanish business Web pages. Using 42 Spanish speakers as subjects we conducted a two-phase experiment to evaluate this portal and found that, compared with a Spanish search engine and a Spanish Web directory, it achieved significantly better user ratings on information quality, cross-regional search capability, system performance attributes, and overall satisfaction. Subjects’ verbal comments strongly favored the search and browse functionality and user interface of our portal. As the Web becomes more international, this research makes three contributions: (1) an empirical evaluation of the performance level of a Spanish search portal; (2) an examination of the information quality, cross-regional search capability and usability of search engines for the non-English Web; and (3) a better understanding of non-English Web searching.
