Microsoft is allowing its Windows Live customers to consolidate their contact lists across different websites with the release of Windows Live Contacts API.
When featured on a website, Windows Live Contacts API allows the 400 million Windows Live customers to integrate their contacts, including their Hotmail, Messenger, and Mobile contacts, with the specific site.
"We thought "˜Wouldn't it be great if you could use [Window Messenger] on different websites?'" said Angus Logan, senior technical product manager for Microsoft
"When I sign into Facebook, for example, why do I need to manually re-enter all of my friends from Messenger or Hotmail?”
