From a semantic standpoint, there is a clear differentiation between the meanings of public and publicized con-tent. The former includes any content that is accessible by anyone, while the latter emphasizes visibility - publicized content is actively made available. As a user's on-line experience becomes more personalized and data is increasingly pushed rather than pulled, the line between public and publicized content is inevitably blurred. In this paper, the authors present quantitative evidence that despite this trend, in some settings users do not anticipate the use of public content beyond the narrow context in which is was disclosed; they do not anticipate that the content may be publicized.
