This post is made from BlogAway, a client app that allows posting and viewing posts on blog directly from an Android device.
From the app, you can publish a new post, save a draft online or on the phone, add links, add photos and movies.
My first user experience was rather tough as I lost the post I wanted to make. I think there should be more confirmations when user actions may end by some lost of content.
But overall, this app is a very good idea that goes in the good direction.
