Enter Indiepaper! You can send a special HTTP POST request to Indiepaper, and it will extract the content of any article on the web (ad free!) and publish it to the Micropub endpoint of your choosing. You can use this functionality with your Microsub server, such as Aperture, to publish these articles for later consumption into a special channel.
