CMS (Course/Contents Management System) is a very useful platform of online cooperative learning and communication in language education. But, though on the Internet, it does nothing but control learners within itself and, in other words, merely enclose them from outside. To begin a new approach to resolve this dilemma, the present writer utilizes social web services, mostly Google and SNS. The former enable the class to share online documents synchronously, serving as a real time wiki. The latter has students'writings revised and improved by correction and comments from online anonymous peers. These activities can meet various needs of learning communities based on the long tail theory, partially removing the drawback of CMS above. As a result, students'motivation seems to be enhanced and have their peer activities stimulated. An integrative balance between such web services and CMS will be taken into consideration in this paper.
