Given the importance of the blogosphere for autonomous language learning, many studies on computer-assisted language learning (CALL) have vigorously investigated the use of blogs in language learning. Noticeably lacking in these endeavors are investigations of language learners' social engagement with others in online spaces to define and negotiate their own meanings of language and language learning.
