Instapaper, on their official weblog:
Since the launch of our new parser in January, we’ve gotten lots of inquiries from developers about using our parser for third-party applications. With the new Instaparser API, app developers can use our parsing tools to provide users with a lightning-fast browsing experience optimized for mobile devices. Data scientists can use the tools to normalize input for text analysis. And hackers can do, well, whatever hackers might like to do with lightning-fast access to clean, standardized web page data.
I can’t wait to see what developers are able to build with this.
