look at how the buttons are used on bernews. Bermudans could care less what people think because they are layed back however the rest of the world example the US were the people are some what different. murders and suicides will go up.

This button will have to be well though out. probably linked to the category of the post selected by the use. however some sheep will still miss categorize their post to enable the dislike button and get there feelings smashed.

if I was facebook I would just leave it alone
