In my previous review of Instapaper, I covered what the service can do for you, such as saving web pages and long emails for viewing at a later time. However, what I failed to expound on was just how extensively the service has been implemented in other popular applications. Twitter clients, news apps, feed readers and others have succumbed to Instapaper allure and embedded a way to save articles to your account in their code base.

Twitter client TweetBot has Instapaper’s service executed in a way that harks back to Steve Jobs’ vision of a multi-touch UI. A simple tap and hold brings up a menu, in which the option to “Send to Instapaper” is at the very top. Osfoora for iPhone also executes Instapapers service in a similar manner, except all it requires is a single tap on a link you’d like to save for later. Chances are your favorite Twitter client supports Instapaper.

Feed Reader Pulse has earned its spot in Apple’s Hall of Fame by offering a beautiful and engaging way to catch up on recent events. Instapaper enriches the experience by allowing you to quickly skim over lengthy news articles, save them and then go over said articles with a fine-toothed comb later.

My favorite iPad (and now iPhone) news app, Flipboard, rose to iPad App of the Year for 2010 by offering a gorgeous way to “flip” through stories, Facebook and Twitter updates. And having the ability to save those tweets, updates and stories is one of the reason for its huge success.

Instapaper is a beautiful, indispensable app and service in and of itself, and the fact that it has been so widely adopted speaks volumes of its creator and his attention to detail. For a complete list of Instapaper compatible apps, check here
