I was searching for a research method that can be used for studying blogs and came across “narrative and metaphor”. This method has been used to understand language, communication and meaning among different actors.
Some more details about it are at ISWORLD Qualitative research page .
Some more information about this method is at “Narrative Psychology: Internet and Resource Guide” and a blog maintained by Vincent W. Hevern.
