Thread ratings were a nice addition to FlyerTalk but not critical to it -- sort of like the proverbial icing on the cake.
What makes me unhappy is that instead of getting rid of the abusers we got rid of the the feature they abused.
The same thing happened with "Reputation", and for a while with "Signature" and Omni.
Those who like to cause problems can use any feature -- including PMs, e-mail, and open posts to do so. We shouldn't be getting rid of any features because of it. We should, however, see the behinds of the abusers.
