Posterous blogging platform gets static pages, customizable from your browser
Posterous' new Pages feature lets you do that with an editor that supports rich text, images and more. In fact, it's the same editor you already use to edit posts on Posterous. If you're using a standard Posterous theme, Pages should already be available to you. With a custom theme, you may have to do a little more work, but the instructions should be easy to follow.
