New Zealand is currently in the middle of a Facebook trial. In an attempt to further explore users being able to agree with or express discontent towards comments written on Facebook Pages.
Underneath each comment, to the left of the like button, you will find an ⬆️ to agree with the comment or a ⬇️ arrow to disagree. In the middle of the arrows is a cumulative total of votes.
This feature is not set to replace the emoji reactions that so many of us use. Although it may potentially help in supporting the platform to respond to and moderate inappropriate content quicker, which is always a good thing!
I my opinion I am not quite convinced yet whether or not this just a different way of doing the same thing? It remains to be seen if this will be a permanent addition to the Facebook interface, with the length of the trial not specified.
