When I created my Facebook account, my idea was to collect friends so I was sending friend request to almost anyone I meet in Facebook. It may have been the remnant of Friendster that the number of friends mattered. But now I came to realize that I should be choosy with the friends that I have because a network is a give and take. That means when I post something the people in my network should react and I would do the same to their posts. Since early this year I had started deleting some friends who do not react to my posts.
