When I was on TalkBoard, I worked hard to maintain an open mind and be receptive to the fact that just because I didn't personally find something useful, others who perceived the world in a different manner might find value in it.

FWIW, I definitely see the use of a feature like this. I'm in the middle as to whether I'd personally use it, but I think it's something that can add value to the FlyerTalk experience for a lot of people.

As for the feasibility of implementing it, I'll just refer everyone to nsx's excellent comments above.
