Facebook survives because of its efforts to improve the quality of relationships and interactivity among users. This is bound by a very fragile thread and can be easily damaged with stupid features like a “dislike button”. Here is what I think.

Facebook has been successful mainly because of its ability to connect people and suggest users to make relations possible, even with strangers.
What makes a social network really “the best” is the way it handles and promotes conversations, and hence establishing relationship among users.
What makes a dislike button really inappropriate? Well, let’s face it. Facebook doesn’t trust its users. The chances of a dislike button being misused are very high. Internet trolls, haters, accidental dislikes, pay-to-dislike-a-post, etceteras are only a handful of examples how the button can be abused. This will discourage conversations among users.
If you like something on a social network, you can choose to like/ up-vote it. If you don’t agree with something, you can simply write in a comment expressing your disagreement. If more people agree with your disagreement, they’re likely to put a like on your comment. This get’s a conversation going and opinions are shared. Conversations make a social network SOCIAL.
Introducing one sloppy feature like a dislike button can quickly destroy the integrity of Facebook. It would be asocial.
See I disagree. Because when the Arizona shooting happened that’s one story someone posted that I would have disliked. I think if Facebook gave the user posting a link the option to add “dislike” it would control how it was used, and mostly likely would only end up on things people would dislike anyway.
Completely agree with you on this….
Facebook is making sure there is no form of hatred on its site, relationships should not be destroyed, but built. Which is a great move from their point of view.
Agree, if anyone wants to give there feedback they can give via comment also by we need a dislike button for that.. I never want a dislike button. And if I want then just for fun (fun of 2-3 mins) not to make anyone feel bad…
I find this amusing as there is now a “dislike” button on Facebook.
