Facebook adds hashtags – ‘#’ – into the popular social network. Honestly, many users were already using before the addition of the feature but now the hashtags followed content will be highlighted as a link.
Hashtags were populary used in Twitter which used to highlight the trending topics on internet, and would make the content a bigger part of conversation. After watching Twitter, Instagram, Tumblr, Pinterest, Google+ and Vkontakte.com already using it for the same purpose as Twitter.
The hashtags generally indicates that it is larger part of discussion. The company’s blog announced “When you click on a hashtag in Facebook you will see a feed of what other people and pages are saying about the event or topic.”
I am pretty sure we are going to see “#sad” as a all time trending topic on Facebook.
