Good first step - rather late and not sufficient though
I welcome that FB has finally realized what a security threat this is and decided to do something with it - at least something - this is by far not sufficient from a user's perspective. Modern malware attacks are often geographically targeted, focusing on a small group of users and controlled distribution to prevent detection by AV vendors. Any solution that is based on central database of known good (or known bad) links is not sufficient. IMO education is the most important part - that FB admits and users understand that there really is a threat. And second most important is to use some security solution that can handle this kind of threats, on users' systems
But at least first step in the rights direction
