I knew Yahoo Buzz was one of the “sunset” sites - properties that would be shutdown by Yahoo. I still kept it on the site, but moved it to the bottom of the homepage. The quality of the articles being voted up have been on the low-end months before its eventual demise was announced; sometimes, you even get spam. The site had also been redesigned to its bare essentials.
The latest version of Digg - aka Digg v4 - is getting a lot of negative feedback from its users, especially the power users. They’ve lead a Digg Revolt by pushing articles from their rival, Reddit, to Digg’s homepage. Now, they’ve defaced the site’s comment system by littering it with anti-Digg comments.
