The already huge number of blogs in existence is increasing rapidly, and many users are struggling to find a way to keep up with the expansion. A number of existing tools aim to capture the general topics of all currently popular topics among the entire blogosphere, while others allow individuals to read a fixed list of blogs. However, few personalized tools exist to help the individual get an overview of the specific blogs he or she reads. This paper presents the concept of social topic extraction via the Smarter Blogroll, which displays current topics for a selection of blogs. While there was little difference in users‘ ability to identify topics using the Smarter Blogroll, the results of our user study point to design recommendations for improving the use of metadata within blogroll entries, thereby facilitating blog reading. The paper concludes with implications for the design of tools to aid in blog navigation and reading, as well as recommended directions for future research.
Email archives are full of social information, including how messages are addressed and frequency of contact between senders and receivers. To study the use of this rich metadata for email management, particularly email triage, we deployed SNARF [Social Network and Relationship Finder], a prototype tool which uses social metadata to organize received email by correspondent, sort received email by past interactions, and filter email into multiple views. We discuss the lessons from a seven month deployment, including the value of organizing by personally addressed mail, the unexpected value of SNARF for email awareness, challenges with handling workflow, and ways to use social metadata in applications.
