[Formerly known as Read It Later] Save webpages to read later, and eliminate cluttering of bookmarks with sites that are merely of a one-time interest. With Pocket, you can read at home, work, on the plane, or during your commute; even without an internet connection.
Pocket is available as a bookmarklet, as a Firefox addon, as several unofficial browser addons, and as a mobile app available for a variety of platforms.
