This post provides an annotated bibliography of some work on using social media (in particular Facebook) as a pre-registration/pre-university/induction tool. The references given can also be found at my Delicious site. Some examples of the use of Facebook for induction purposes are given at the end.
CommentPress is an open source theme for the WordPress blogging engine that allows readers to comment paragraph by paragraph in the margins of a text. Annotate, gloss, workshop, debate: with CommentPress you can do all of these things on a finer-grained level, turning a document into a conversation. It can be applied to a fixed document (paper/essay/book etc.) or to a running blog.

"When you create an account, you designate yourself as a teacher or student. Teachers can create groups that students join when they create their accounts (students can join multiple groups and teachers can create and/or join multiple groups); when a group is created, the site generates a group code that must be entered to join. Then, messages, files, links, and assignments can be sent to whole groups."
