Should rewards for asking good questions be improved?
I've noticed (particularly with the larger scale sites) that there are a number of good questions that receive many answers, and yet no one bothers to up-vote the question. It seems that honoring a question with an answer is an implicit endorsement, so why not give a point or two per answer, so that folks in the community who ask good questions are not 100% dependent on people up-voting?
Edit:
I suggest that answering is an endorsement simply because you have already determined that it is worth your time to respond, and I assume you place some value on your time. This obviously doesn't apply in Meta, but elsewhere.
Maybe it would make sense to award 2 points per answer, and then if someone answering actually up-votes the question, you could give an additional 3.
