Ericka Menchen Trevino has put her final (almost) Masters Thesis online. It is entitled Social Bookmarks: Personal Organization and Collective Discovery on the Web
From the summary:
My findings suggest that people understand their own posts to del.icio.us as a memory aid as well as a sign of what they value. The posts of others, when aggregated, signified the interests of del.icio.us users as a group, and social trends on the web. It is possible to analyze this content much further, and while only a few do this infrequently, it is still an important development. The posts of other users often derived significance from prior knowledge of the individual. In the less common case of a browsing an individual account without any outside-del.icio.us information about that person, the posts were taken at face value, which depends on the browserâ??s prior experiences and purpose.
After a quick pre-reading it seem very good. I am looking forward to reading it more carefully later.
