Facebook is adding on to this already great feature.
They are adding an iFrame version to the like button which means when you like something you can leave a comment or longer story for all to see. For example, if you see a dress online and you "like" the picture, now you can add a comment to your like and say "That's a really cute dress, does it come in blue?"
Facebook is also allowing you to send out messages to specific users who "liked" a certain product, brand story. For example if you "liked" an eyeshadow on Mac's website, they can send a special coupon, or just a personalized message to you and the others that liked that specific eyeshadow. This will work really well for targeted marketing. Looking forward to Smashyn implementing these new features into our sites.
Want to know where people are clicking on Facebook? Now you can. Facebook now allows a fb_parameter to be added to show you what kind of stream the click was, and where the click happened. It also filters out people's private information allowing you to see the anonymous URL.
