Facebook, one of the fastest Growing Social Networks has a Friend Limit (if you know). It says that any user cannot have more than 5000 friends. Now The reason behind this is unclear. May be it’s because they don’t want people to spam. Twitter also has a limit of 2000 Follows and this limit can only be lifted if you have 2000 people following you.twittermark

Now what’s the news is that recently Mark Zuckerberg (the guy behind Facebook) had posted a status which clearly stated that Soon Facebook users can add unlimited friends. This is not confirmed but this may be a possibility in near Future. This would give another boost to Facebook and then people especially companies will use Facebook as a marketing tool if they can make unlimited friends.
