Yahoo! Mash
Yahoo! Mash was a social network service launched by Yahoo! during the early part of September 2007, to compete with other social networking sites by offering "mashups" of existing web services on a single-user interface. On August 28, 2008, Yahoo! announced via email to its subscribing members that Mash would be shut down on September 28.
