Cross-site activity stream aggregator cum social bookmarking service FriendFeed has answered the loud calls of users and developers and today released the first version of its Application Programming Interface, or API. Good news as this may increase its popularity just like Facebook’s API.

We are very excited to announce the launch of the FriendFeed API, which enables developers to interact with the FriendFeed site programmatically. It’s designed to make it possible for anyone to improve FriendFeed or integrate FriendFeed into other applications.
