The growing popularity of a school-wide e-portfolio system in colleges and universities has raised concerns regarding whether students will use it or consider it important to have an e-portfolio system, especially when its use is not required by their curriculum. This study investigated college students' intentions to use and the students' attitudes towards using an e-portfolio system, and did so from the perspectives of career-commitment status and weblog-publication behaviours. The results indicate that career-commitment status substantially influences college students' intentions and attitudes relative to using an e-portfolio system. Also, overlap in the functions of weblogs and e-portfolios (which allow people to use them interchangeably) does not directly result in higher or lower levels of intention to use an e-portfolio system. A composite system providing career services, goal-oriented self-presentation and personality-driven self-expression is recommended.
