This phenomenological study examines the motivations and experiences of librarians who author professionally-focused Weblogs. I constructed a model of librarianship based on Wilson and Buckland. The results show a close fit between librarian bloggers and the ideals of the field as expressed by two primary library and information science philosophers. A Web survey generated 239 responses to demographic and open-ended questions. Using the results of the survey, I analyzed demographic data and performed a phenomenological analysis of the open-ended questions. A list of category responses was generated from each set of answers via the coding of descriptive words and phrases. Results indicated the motivations of librarian bloggers are based around themes of sharing, participation in community, and enhanced professional development. Respondents reported feeling more connected to the profession and to colleagues across the world because of blogging. Respondents perceived the librarian blogosphere as a community with both positive aspects - feedback, discussion, and support - and negative aspects - insular voices, divides between technologists and librarians, and generational rifts. Respondents also reported an increased ability to keep current, improved writing skills, and opportunities to speak and contribute to professional journals.

More than half a billion people use Online Social Network Sites (OSNS) today. They disclose personally identifiable information such as names, date of birth, email address, phone numbers, and home address on their profiles. Some OSNS users also disclose their political and religious views and personal interests. The huge commercial potential of OSNS users’ information and the integration of OSNS with third party advertisers and/or aggregators pose threats to users’ privacy. This thesis reports a study which contributes to our understanding of the form and nature of online privacy by critically analysing the privacy concerns related with the failed launch of Facebook’s advertising tool Beacon. Beacon is an interesting case study because it highlighted the privacy concerns of OSNS users. Qualitative data was gathered from 29 weblogs (blogs) representing user opinions (492 comments) published between 6th November 2007(when Beacon was launched) and 28th February 2008 (when commentary had dwindled). A thematic analysis of the blogs contributed in the development of a taxonomy of privacy concerns of OSNS users specifically related with the third party information use. Noticeably, the concerns such as commercialism, terms of service (TOS), lack of user control, lack of user awareness and data protection influence user perceptions of online privacy. The limitations and key implications for designers and service providers of OSNS are also discussed.
