Character Blogs

For the randoms who come across this site and don't know me, I have an entire universe of characters living inside my head (very crowded, occasionally loud). The universe has a history and the characters have backgrounds and relationships. I've been toying with the idea of writing blog posts from different characters' points of view on my so-neglected-it-might-as-well-be-dead fiction blog. Via Whedonesque, I found a blog post about the potential marketing value of character blogs (for characters already established in other mediums). I think it could also work as an artform in and of itself. If the author is motivated enough, which, apparently, I'm not.
