Fb:comments Tag No Longer Notifying Users

In accordance with a news item Facebook posted last Thursday, the fb:comments FBML and XFBML tag will no longer send notifications to users when another user replies on a particular comment board. Oddly, this change was not mentioned on the Developer Roadmap, and seems to have caught several developers off guard. Facebook says this change is to ensure that “users aren’t surprised after they post content in comment boards”.
