Social Network Sites: Definition, History, and Scholarship
Social network sites (SNSs) are increasingly attracting the attention of academic and industry researchers intrigued by their affordances and reach. This special theme section of the Journal of Computer-Mediated Communication brings together scholarship on these emergent phenomena. In this introductory article, we describe features of SNSs and propose a comprehensive definition. We then present one perspective on the history of such sites, discussing key changes and developments. After briefly summarizing existing scholarship concerning SNSs, we discuss the articles in this special section and conclude with considerations for future research.

Mark Cuban, Facebook, and OpenSocial.
Microformats Operator
Operator demonstrates the usefulness of semantic information on the Web, in real world scenarios.

Michael Kaply's blog
In creating Operator my goals were to create something that was useful to microformat developers as well as users looking to explore microformats. As such, the Operator Toolbar can be displayed in two modes: Microformats mode and Actions mode.

Feed2Mobile. I probably would never have read them fully on a computer.)
