Yahoo may have beat them to it with the launch of its Digg clone, but MyPunchbowl too wants to announce something called “Buzz”, this one a Facebook News Feed clone of sorts for party planning.

MyPunchbowl Buzz will give hosts and guests alike a way to keep track of what’s going on with the party scene as organized through the site. Initially it will consist of the onsite info stream shown below, but there are plans to expand its scope to include RSS, instant messaging, and SMS-based notifications as well. An API will eventually be provided for developers to leverage the Buzz data for whatever purposes they desire off-site.
