Blogdesk?
 

Has anyone ever heard of it or even used it for their blogs?
I just came across it the other day and its a program that'll let you make posts on your blogs offline, and when you get online it'll update them in an instant.
I havent tried it but it seems like it would be very helpful especially if we're working on hundreds of blogs a day.
