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.
"I own the collection of comments on my blog, and you own the comments you've placed on my blog and all others. I should be able to back up a complete set of comments on my blog, and also back up a copy of all comments I've placed on all blogs."
"The smart thing to be doing online these days is tumblelogging, which is to weblogs what text messages are to email - short, to the point, and direct."
