Digital technologies have become an important part of language learning and teaching across the globe at various levels of education. The advances in question have altered texts and tools available to teachers and students and have given practitioners and researchers a new understanding of L2 literacy development. More specifically, the successful attempts of integrating the blogosphere in language education suggest the improvement of L2 writing. Through blogging, students are given the opportunity to use the new language they are learning and new technologies to strengthen social bonds and express their thoughts and reflections on the online platform. This chapter elaborates on the use of the blog in teenage learners' L2 literacy in the digital age, and examines the impact that blogs have on the authorship, personal expression, writing fluency, and confidence of the L2 teenage language learner. The chapter also offers a theoretical, practical scope to establish the full perspective of integrating blogs into the language classroom.
