Blogging on the move is already made possible by having Tumblr and Wordpress application on apple app store. However there isn't a decent app for blogger. I am using Blogpress lite now as an alternative to blog on blogspot using my ipod. It can manage serveral blog on different host. Not very comprehensive but still consider complete to at least post a post with pic. Busy person who want to post entry without wifi can look into this app. It can save your draft till u reach a wifi spot to publish it. - Posted using BlogPress from my iPhone
