Facebook Connect is now open. Facebook Connect is essentially a registration system that allows just about any website to let its user login with their existing Facebook login. People who login will be able to share information and actions on your site and network with your different visitors. There is a lot of potential which is why companies should jump at this opportunity. Adopting Facebook Connect will surely increase activity on your site, and certain events can be relayed back to the users news feed, which could help virally push your site to thousands of people.  With Facebook’s 130 million active registered users, Facebook Connect is surely poised to takeover OpenID and all other competitors. I can really see many companies adopting Facebook Connect in the coming months simply because of the large user base and potential for viral marketing.
