The third-party users can log in using their Twitter account and collect information and content from Twitter. A specific functionality or tool called @Anywhere will allow the third-party users to tweet or share information from other sites directly onto Twitter.
Participating sites in the initiative include Amazon, AdAge, Bing, Digg, EBay, The New York Times, Yahoo and YouTube. The functionality is reported to be akin to Facebook Connect.
Last week, Twitter launched location-based functionality which allows users to show the town or city they are tweeting from.
