This study investigates how social media, in this case Facebook, can be incorporated in ELT through e-dialogue journal writing shared in a Facebook closed group. Fifteen EFL students participated in this case study. They were second, third, and fourth year students of English Education Department of a university in Bandung, who voluntarily joined a Facebook closed group for about four months and contributed their journal entries. The content of the students' journals and responses in this closed group were analyzed to identify the nature of the students' journals, the patterns of interaction, and their responses to e-journaling through Facebook. The findings indicate that the students responded positively to this activity and perceived improvement in their writing especially in vocabulary and grammar. The power of learning and sharing from others is also emphasized.
