Nowadays, with the increasing use of web applications such as online favorites, online readers, etc., we tend to place a large number of sharing buttons on the browser for convenient daily use. However, sometimes these sharing buttons are just too many, making the entire browsing interface look very bloated. In this case, the service AddThis! can effectively solve this problem. AddThis! acts as a sharing intermediary service; through it, you can consolidate the services you frequently use into one button, which is convenient and practical.
Before using it, you must install an IE or Firefox extension. After installation, a button like the one in the figure below will appear on the browser's navigation bar. When you enter a blog, it will automatically recognize the Feed address, then press the subscribe button.
