This document provides a case study of Cloudworks, a social networking site designed for educators to share learning and teaching ideas. It describes the development of Cloudworks based on educator needs, theoretical underpinnings of object-oriented sociality, and an evaluation of its use for an Open University conference. Cloudworks allows users to create "Clouds" to discuss topics, and organize them into "Cloudscapes". An analysis of a conference Cloudscape found high participation, with 47 Clouds created and over 3,000 visits, demonstrating how Cloudworks supports online communities.
