I’m reluctant to use SO to ask questions based on most of the responses here, and rarely have the opportunity to contribute, but I did have a surprisingly good interaction a couple years ago. I’d googles around for some esoteric solution, and eventually honed in on a 95% solution on SO. After figuring out the last piece I went to add a comment to the accepted answer with my details based on my setup, but didn’t have enough karma. So I added my solution and apologized about not having the karma and it belonged as a comment to the more complete answer, and forgot about it. Next time I’d checked back, I found someone had given me the karma to comment. I didn’t even know anyone could give karma, but it certainly wasn’t from upvotes. So that was maybe a rare nice event on SO.
