Deprecating an API is a bad way to go, especially if the API is fairly new. This post is telling me two things:

1) Dropbox's API was not designed correctly the first time. It should not just be a representation of their internal stuff exposed publicly. It needs to be designed first. 2) Dropbox is struggling to understand the difference between providing a consumer product (like their normal Dropbox product) and a developer product, like this API.
