I just started hosting activeweave, a project I have been working on in my spare time. For now, it is a simple web-logging platform offering free weblogs to authors, both in French and English (years at Oracle have taught me to build internationalization into the very early stages of any design effort). It has the basic capabilities you should expect from such an engine, letting you upload and post photos, and allowing you to customize the look and feel of your weblog entirely, thanks to a template-based approach on top of a Java Server Pages infrastructure and custom tags. Ultimately, my goal is to turn activeweave into a laboratory, with dynamic features introduced to measure how they enhance teamwork models, by mixing workflow events with authoring, editing and annotation tools, thus streamlining a lot of the processes at play when building and maintaining technical knowledge in a group.
