Facebook is advancing
You may have already heard about Facebook's new look as they change the social experience for users. While still focused on the Individual as the center of the experience, they are adding more capabilities. In particular, I'm amused that they are finally catching onto the idea of multiple tabs each per application, although they have not moved to free form tabs like developerWorks Spaces, netvibes and other sites. Separating the app to a different tab helps to create shorter, cleaner front pages, by compartmentalizing and creating subtopics. However, it is better if it is not limited to a single application; after all you might have several tools and widgets to focus around the same topic.
PS: I'm trying out AddThis, a service that lets users redistribute any URL to over 30 other social sites, saving me the trouble of adding links to digg, del.icio.us, etc. manually.
