The app looks great. It's simple and it does exactly what it is supposed to do.
You can edit existing articles, add new and embed images (although they always come at the end).
It also has an option to include the relevant labels.
Perfect for simple updates.
Oh, and it's free, and we all like FREE apps.
I'm actually writing this post from the iPhone Blogger app. Let's add some images and see how it comes up.
