How Facebook is beating Twitter hands down:

FOR EVERY 5 NEW USERS ,4 USERS ARE SIGNING UP ON FACEBOOK   VS ONE ON TWITTER 

 In spite of its heft valuation, Twitter's growth has stunted as Facebook continues to grow..leaving twitter far behind. How Twitters growth has declined can be seen by this chart above.Starting off with 197 million active users in Q1 2009, Facebook added 411 million users within two years. Twitter, having had 204 million users in Q1 2013, only managed to add 84 million to its user base during the same time frame.  Facebook is beating twitter by 5: 1

One of the major problems Twittereems to be facing  is that there a lot of churn — lots of people sample the service and then stop using it. And it may be that Twitter, which has its own particular set of customs and expectations — try telling someone who doesn’t use the service what “retweet” is, and how that differs from a “modified tweet” — may simply be more of a niche service than Facebook.
