This is just tossing an idea out there to see what the SO swarm thinks.
The idea is that you would be prevented from downvoting any answers to questions where you have your own answer. It seems to me that this would prevent the mini-wars I've sometimes seen and be fairer on all involved.
You could either choose to answer or choose to vote. You can't upvote your own answers, why should you be able to downvote "competitors"?
Obviously it's needs some more thought with regards to what happens when you vote, then answer, for example. And I realise it might cause some angst for questions you've answered where the other answers are absolute rubbish. But I believe I would be happy just to point out the problems with the answer (in a comment) and let the swarm decide.
Any thoughts? Am I just spouting rubbish?
