Facebook is reportedly helping you unsend a message on the app to someone and will give you 10 minutes to do so.
According to Mashable, this was in Facebook's release notes:
I kind of wish they had this feature for actual text messaging because it would have saved a lot of relationships and friendships for me! Haha!
Is this something you will use? Will this impact the future of Facebook? Do you use Facebook in this way? As you can see, I have a lot of questions!
