I´m thinking about a system for editing individual videoclips, from videoblogs, into sequences which then can be stored as SMIL-documents in the editors blog. Afterwards the sequence might re-edited and stored as new versions by others without changing the original sequence or the video-clips. From now on I will refer to this concept as "wikivideo". Actually I´ll probably end up writing about the wiki-like part of the system more than about the blogging part.
