I'm not gonna lie, I love and take delight in every point I get (they're mostly irrelevant and useless though). But I want this fulfilled not for points, but because it drives me nuts seeing a resolved question without a BA. Like X-Scizor said even if they like the answer one question then leave users would leave the questions un BAd.

In my experience, its much faster to get promoted manually than by getting points to expert. Just give it like 4 years...
