If you have a Yahoo email account, you should probably go change the password right now considering there is a chance that it could be one of the many stolen passwords.
Today, we're excited to introduce our new commenting system, powered by Facebook. Starting right now, you can comment on and "like" our posts right on the site using your Facebook login, and share them instantly with your friends on Facebook, too. You'll also be able to post when logged into a Yahoo account (and even more ways to comment coming soon).
