Some people with pervasive developmental disorder (PDD) can hardly express their own thoughts in language. Sometimes, they have been considered as a communication disorder. However, since the word “communication” is usually defied as an interaction between at least two persons, it is doubtful to attribute problems happened within a particular communication to one side. In this study, I collected text data from a mi-croblog of one person who has been diagnosed as PDD and having difficulty to express her own thoughts in language, in order to investigate how the microblog had changed the way of communications. The results of the text data analysis showed that the par-ticipant expressed what she wanted to say by referring and utilizing remarks of others. The possibility and implications of removing the difficulties from their communication through the process of “curation” was discussed.
