Google announced several new Google Buzz API features including “Google Buzz firehose,” with firehose, all public activities are available as they’re published with a single subscription, thanks to syndication via PubSubHubbub. “We’ve had some fun coming up with cool things to do with firehose. For e.g., Bob Aman coded up “Buzz Mood,” an App Engine app inspired by Twistori. By scanning for posts that contain certain keywords, Bob’s able to give us a sense for the mood across all of Google Buzz in real time.” Integrating with firehose are Collecta, Gnip, OneRiot, Postrank Analytics, and Superfeedr’s Track,” states Google.
Features include: Comments by user – This feed consists of activities the user has commented on; Likes by user – The activities the user has liked are in this feed; Shared counts – This’ll return the number of times a specified URL has been shared across Google Buzz.
