Facebook Testing Pop-Up Messaging

Facebook is in the process of testing pop-up messages that tell people to read a link before sharing it.
SIx percent of Facebook’s Android users will take part in the test that is aimed to get users to “be more informed” about what they share on the platform.
Twitter did the same type of feature in June of last year.
Do you think this feature will work? Are you more careful about what you post on social media?
