Twitter killed any plug in not Oauth compliant on August 31st, 2010. That stopped comments from feeding to the MLR Twitter account. After hours of searching I finally found the problem and a plug in that will work. The new plug in only notifies that a comment has been made, it does not display the comment. But, unlike the old plug in, it does tell you what post the comment was made on. One hand giveth the other taketh away!
Well it seems to work for me but but not other users. Sigh…
