Facebook Connect and your website
A question in the wake of the announcement of Facebook Connect, which will allow people to log in at many sites with their Facebook ID: "If a user registers on your site but does so through a third party, can you count her as one of your registered users? This isn't a theoretical question. Publishers will have to ask this, and many related questions, as this era of openness and portability creates new challenges for digital media."
"Brands should watch how this impacts the few launch partners first, let them sort out the bugs, and put this on the roadmap. Brands that have websites that have social actions (such as buying a product, rating, ranking, or leaving comments) should keep this in mind, as they can now extend the actions to Facebook streams.
"Brands that are already trying to reach the Facebook audience (white collar workers and college students) should plan on experimenting with Facebook Connect as it can bring additional social functionality to corporate websites."
