Meredith Farkas has created Five Weeks to a Social Library, a site that includes many knowledge artifacts from a well-structured online course. The material is not just for librarians, with an outline that looks like this:
Week 1: Blogs
Week 2: RSS & Social Bookmarking
Week 3: Wikis
Week 4: Social Networking, Flickr & MMOGs
Week 5: Selling Social Software
Successful Completion List
The structure is similar to the informl learning unworkshops we conducted last year, but what I really like about this site are links to the participants, their blogs and their final projects, so you can follow the learning process. The site is built on Drupal, an excellent system for multi-user blogs and community resources.
Note that Week 1 covers blogs, which I have come to see as the primary building blocks for the social web. One reason that blogs are so persistent is because they are personal, and owners take pride in their maintenance.
