Sorry if this has been posted already...I looked but didn't catch it if so. Described as a "Journal for understanding the social and psychological impact of today's social networking practices." More than a few interesting articles here, some with full text access.
Kerianne, I ran a search and did find several articles from this journal in RUL.
Also found a journal called Ethics and Information Technology that had some relevant articles. Carrie, your journal sounds interesting as well.
Open access journal devoted to entire scope of matters related to the Internet. A quick look shows articles on privacy, inclusion, data collection, open source, censorship and many other topics that could be considered part of social informatics research.
A couple of interesting bits from this article: "Data is the authorized way to pursue self-knowledge in the networked society; the other means are suspicious, deluded or outmoded."
And on the matter of FB and specifically, the way in which the timeline feature shapes us while serving them: "The more work we put into making a coherent story out of the data Facebook collects, the more useful, marketable information we give them."
