The world’s largest social networking website Facebook now supports hashtags. Hashtags are the simple keywords prefixed with the sign #. Websites like Twitter, Instagram, Google+ and now Facebook also uses them for identifying discussed topics.Users can search for them or simply click them and find posts shared by the users world wide without any limitation of followers, connections etc. For example if you search #wordpress in Facebook, it will show you the posts shared by the Facebook users world wide and this way you can also know what others are discussing about WordPress not just your the people you are connected with.
