A few months ago we added Notifications to the WordPress.com Toolbar and recently we released a Chrome extension so that you can always keep up with the activity on your blog. Today we're adding comment notifications, complete with comment moderation and reply functionality.  When your post receives a comment, you'll get a Notification that looks something like this:

If you're using threaded comments, you'll see if someone responded directly to you, right in the notification.

You will see Approve, Spam, and Trash links in your comment notification if you have permission to moderate comments, allowing you to moderate the comment from within the notification:

Clicking Reply automatically approves a comment and displays an area for you to type a reply in. When you're done, just click Reply and you can get back to whatever you were working on, without having to navigate to the dashboard to manage your comments.

You can still manage comments in your dashboard, but we hope you'll find the comment notification a convenient shortcut.
