My intention, and attempt, is to provide necessary feedback through the reputation. I have never supported calling someone out in a thread, and often get tired of seeing the many attaboys in a thread.
I have used, and will continue to use, the function for which I believe it is intended. I have submitted a negative to someone that 1) asked a question and then 2) attacked the person that responded because it wasn't what the OP wanted to hear. Completely uncalled for. On the positive note, I chose to communicate through the reputation an attaboy for some piece of information that was helpful to me, as well as other FTers.
As for reviewing posts in threads, I'm mixed on reputation. In the UA forum where I spend the majority of my time, I've come to know who to trust, and who are trolls. Reputation may come into account when it is someone I don't know.
Finally, I have no problem "dinging" a troll. There are some posters that have nothing contructive to say... and that is my definition of a troll. I'd prefer that poster not post anything at all.
