I was over on stack overflow and a user asked a pretty simple question about a HTML layout. (The question can be found here: http://stackoverflow.com/questions/3196859/3-column-web-parts-page/3196934#3196934)
He accepted an answer, which, in my opinion, was a bad answer (i.e. I would never offer this advice to people starting to learn HTML / CSS.)
The user is happy, because it was an easy way to do something, but I am unhappy as I feel it is wrong and if someone searches for this question and views the answer, they will apply this method too. It is quite a common answer and I am doing to assume that it will recieve no more down votes due to low views.
The other user that answered the question with the bad answer is stuck in his/her way and voted my question down, when it is clearly a better answer than his (not that I care about the down vote, it is just the principle)
What is the best way to deal with it?
