Firstly, I built text-to-speech playlists so I'm glad that you're enjoying that feature and making good use of it. It's kind of a weird one but good for driving commutes, etc.

I'll reiterate here that Instapaper will remain as a separate app, with separate functionality, and a focus on the reader. There are no short-term or long-term plans to modify the user experience of Instapaper.

In the blog post we detail that "Instapaper provides a compelling source for news-based content" for Pinterest, and that portions of the parser technology will be used throughout Pinterest.

For Instapaper, it means leveraging the technical expertise, support, and resources at Pinterest.
