Dave Winer on Twitter's new @anywhere identity system extension

“Dave Winer on Twitter’s new @anywhere identity system extension. What is @anywhere? Here’s my best guess…” @Anywhere was a new feature announced by Twitter that allows websites to integrate Twitter functionality, such as displaying user profiles and enabling commenting, without users having to leave the website. This is Twitter’s answer to similar features offered by Facebook, where users can use their Facebook login to interact on other websites. Dave suggests that @Anywhere appears to be part of a broader trend of technology companies trying to extend their reach and integrate their services across the web, though the long-term impact and usefulness of such features remains to be seen.
