If you are looking for something similar to Digg, you might want to take a look at the newly relaunched and redesigned Yahoo! Buzz Beta.
Yahoo! Buzz used to be something similar to Google Hot Trends, and they still offer a similar service, but they have made the trend results votable by the users of the site. Much like any other social news site out there. I don’t really think this site will take off, but it is a definite step up from what it used to be.
