‘Like’ is abused on facebook

Recently in Taiwan, a man posted a message on facebook. He asked people to chick ‘like’ because his future father-in-law said if he did not get 500,000 ‘likes’ in 2 days on facebook, he would not let his daughter marry him. Of course, this man got over 500,000‘likes’ on facebook because facebook is popular these days. And another day, I got a message from the facebook that saying 2 cute children take took a board in the photo. The board says’ father told us if we got 1,000,000 likes on facebook, then he will would take us to the Disneyland.’’
From These stories make me believe facebook is really a popular social network, we can review our friends’ activities and share messages and photos with them easily. I think it is a good media/medium to connect with friends. However, how can we "like" the strangers' activities when we know nothing about him them? How can you we trust the strangers' "likes" and use them to judge a love in your our real life? With the development of the world progressing (There should be a better way to say this though), internet and social networks are changing our life. However, there is something that can not be changed, includes including love and caring.
