There's definitely a trend towards more and more cryptic or downright stupid thread titles -- not to mention titles with gross spelling and/or grammatical errors.
I agree that putting more complete information (such as promo dates) in thread titles would be helpful, but the trend is, unfortunately, in exactly the opposite direction.
And by the way, the word is "targeted." FlyerTalkers are such horrible spellers that most of them don't even get that one right, as easy as it is.
