About Blogspace
"First, Blogspace sites can be easily edited over the Web, through any web browser. (We're also thinking about adding support for WebDAV and other formats.) Second, Blogspace sites can hold not only text, but also structured and semi-structured forms of data. Third, Blogspace sites use a powerful linking system to let you categorize and manage all of your information in a permanent and useful way."

Some promising stuff, such as keeping track of outside links, support of revisions, and a mission statement to make the semantic web happen.
