Hello everybody, We have just started an ethnography (online and offline) to study the extent to which the social web can mitigate isolation and loneliness feelings among the elderly by promoting their interpersonal relationships online. I appreciate if you can point me to articles discussing whether the researcher has added the participants to his/her social network site (e.g. Facebook) or has created an specific profile for the research. We have decided to add the participants to our SNSs, creating a group for them, but I would like to know what other researchers have done and the challenges of this methodological decision they have faced. Apologies beforehand if this topic has already been discussed in the list. Thanks, Roser Roser Beneito-Montagut Senior Lecturer School of Computing, Multimedia and Telecommunication Open University of Catalonia Barcelona
