Today is the big day. The brand new Digg that was previously available at new.digg.com will finally replace the current version of Digg. Going to new.digg.com redirects you to digg.com, however both are down. Plus, Digg CEO Kevin Rose tweeted "Launch day!, Digg v4 here we come" just this morning along with this photo (above). Will there be any other surprises that will come with the new Digg when it officially launches? And will we finally see, after an extended delay, the launch of Chatroulette v2 today as well?
