The present work aims at investigating meanings and functions personal blogs have been performing; the personal ones, for their own authors - as some space for self- writing. Towards that, a bibliography research of other forms of written self-account was initially carried out, inaugurated in different periods of History, since Antiquity. Subsequently, a qualitative research was developed, in which ten speeches, extracted from blogs written by women, were analized. This analysis led to some categories to be further discussed, related to the functions the blogs in reference apparently perform for their authors, to the destinations of the posted messages and, still, to the different levels of self-expliciting present in them. The results of this research revel the blogs to be an hybrid type of selfwriting, which gathers some characteristics depicted in personal diaries, others, commonly found in intimate correspondence and, finally, some characteristics of self-writing forms, destined to posting.
