Have a favourite Facebook app ? You may be seeing a lot more of it. Facebook have announced they will allow Facebook apps to be displayed on websites outside of Facebook.com. It uses a simply iFrame trickery to make this work.
For companies who have spent time and money building Facebook apps, this now makes it an easy win to duplicate the application on their own site.
Depending on the implementation this could turn out to be the most annoyance for consumers, only time will tell.
