There is a failure in the process to post comments under news items on the front page of macnn.
If one types a comment without adding a title, then submits, the browser refreshes to the story, doesn't post the comment, offers no warning or indication of problem.
On more than one instance I've taken the time to post, but not felt my comment needed a title as it was just a response to the thread discussion.
If you do indeed feel a title is necessary than a warning should be issued, the text should reappear with the option to resubmit the post with the title!!!
Or, better yet, eliminate the NEED for the title...
