The Washington Post, Time magazine and Boing Boing are all getting a button to send articles to your Kindle. Convenient!
Amazon already has Send to Kindle apps for Chrome and Firefox, but they aren't as widely used as stuff like Instapaper or Pocket — and those services are notorious pains in the butt to get working on a Kindle. So a button on sites denoting that stuff can go to your Kindle should be useful, not just for letting people send stuff but for letting them know they even can. [Amazon]
