In conjunction with its broader initiative to experiment with different ways of making Tweets interactive, Twitter today announced another new development: Twitter will display a list of sites linking to where a Tweet has been embedded. Listing where a Tweet has been used is another sign of how Twitter hopes to continue to make its platform more interactive and cross-platform across the Internet. This means that Twitter can sell itself better as a broadcasting platform that makes advertisers hungry for promoted spots – rather than taking a best guess about where the Tweet goes after it’s sent.
