Neutralike for Facebook
This extension removes the ability to 'Like' things on Facebook, hides 'Like' counts on posts and comments, removes 'Like' notifications from the notification dropdown (beta), and softens the UI notification colors to be more neutral. It does not remove your ability to 'Like' pages, nor does it hide 'Like' notifications in the minifeed (yet). Why? It's too easy to fall into the trap of mindlessly clicking 'Like' on posts and comments instead of taking the time to engage and leave thoughtful commentary. Facebook does not mind this; they're not currently in the business of monetizing your thoughtful commentary. Further, the reward center activation that comes from receiving 'Likes' (which includes the big red notification badge, which I've chosen to soften) keeps us spending more time on the site, deriving worth from (and thus expending effort to receive) this form of social currency. This is also by Facebook's design, enabled by our implicit consent. By doing away with the whole concept of 'Likes' as much as possible, it encourages you to put time into crafting actual messages to your friends instead, and frees you from the need to see how many imaginary internet points your posts and comments have received.
