Grid-Blogging

Grid-Blogging = simultaneous blogging on the same topic.

"The concept of "Grid-Blogging" (more recently called a "Blogposium") has so far consisted of creating a starter-subject, like the word "brand", and getting a huge amount of different (diverse) people to write about it, building conceptions about the subject. Then either using the "trackback" feature in the blog software, or a social bookmarking system to track the participants posting about the subject."
