The Elephant’s Graveyard: 2.72MM abandoned blogs

A new study of blogs and bloggers suggest there are about 5MM blogs out there–only thing is, roughly 2.72MM of them have been abandoned and are floating around like spare parts in space.
Does this mean bloggers try out blogs–date, let’s say–before growing experienced enough to commit?

Mediapost’s interpetation of this data–they say it means no one is paying attention. Axcording to the Mediapost writer, Perseus COO James Henning said, “The average blogger is a teen-age girl who updates her friends and classmates on her life, with words and spellings not quite as informal as instant messaging, Perseus said. Updates are done twice a month.”
