This research investigates blog usage pattern of college students and gender difference. The 25 statements developed for this study were used to measure students' blog usage, gender difference, attitude, and satisfaction toward using blog. The 25 statements are categorized into four areas: information sharing, social communication, management, and negative effect. The findings indicate that the students primarily share and disseminate information with blog. Contacting with classmates and providing details on personal life also seem to be important to students. Female students consider security issue more importantly than male students. Male students show more positive attitude than female students toward using blog. However, there is no significant difference between male and female students in satisfaction toward using blog. The authors suggest blog will have to become more satisfying students by way of more targeted communicative content or by more interesting value.
