Pocket is a great tool for saving your reading/articles for later. Sometimes you will read something and want to save it for later to reference. Pocket lets you do just that. Often there are articles that I save to pocket simply because I am not prepared to do something with the information yet. It also can be used if you don't have time to read an article at that time but find the article interesting enough that you will want to read it when you would have the time.
