It seems like the majority of questions that I come across on SO never get the official green checkmark from the original poster.
When an answer is given that the OP accepts, sometimes they leave a comment under their accepted answer, sometimes they upvote it, sometimes they don't do anything. It seems like only rarely do they hit the green checkmark.
Is it because folks don't know about it? Or they don't care? Or is there some other reasoning with regards to the way reputation works that I'm not aware of?
I have only asked a large handful of questions but I always make sure that I hit the green checkmark on the answer I accept because I feel I need to give credit where credit is due. But I just want to make sure I'm not missing something here.
