When you come across lengthier articles online, you tap the Instapaper button--whether in your browser, RSS reader, or Twitter client, or in any of the many other apps that integrate with the Instapaper service.

You're left with just text and images, and you control the font and brightness and all that other good stuff. The app also makes it easy to discover other good Web content to read, based on your friends' suggestions.
