Facebook added a new twitter hover card like feature to its system. It’s a hover card feature.When ever you glide over any name in the facebook, be it a person,group,page etc. You will see a hover card with total number of mutual friends and “send a message” option,if you hover over a person’s name. If it’s a page, you could see the total number of people in the group/page.
So are you in love with this feature?
