"Over the past two years there has been a lot of discussion about the closure of Yahoo! 360° and the transition to our new profiles experience that we"ve had in the works. Today, we"re able to firmly say that on July 13, 2009 Yahoo! 360° will be closing down and you"ll be asked to move into your new profile on Yahoo!, by July 12, 2009," goes the blog.
Launched in 2005, Yahoo 360 was a social network/blogging service. However, the service could never really gain popularity. In Sep 2008, Yahoo also shut its other social networking site, Yahoo Mash.
