I'm late in that thread, but it's a terrific idea Sanjeev. With that thread, we go back IMO to one of the basics of this message board that make it truly unique. By the way, I've notified that the board have been more "quiet", respectful, civilized and productive over the last week or so. It's great!
Regarding the general karma of a poster, I also agree with Sanjeev, but some of us might remember the "Recommend" post feature of the old board and, to me, it was something valuable.
Cheers!
