Facebook Connect has been launched and now with the help of the same you can log onto other web siteswith your Facebook ID. The application was first announced way back in May 2008 but has seen the light this month. The bets part is that with Facebook Connect you can even see what your friends are up to on varied sites.  

This application is very much like the OpenID but the differentiator is the propriety code, which is not open. This is a great thing for Facebook as it continues building and strengthening its social graph by trying to replace all logins with their ID.

Facebook has even announced that major sites like SF Chronicle, Digg etc. would be incorporating Facebook Connect very soon.
