This question already has an answer here:
I just saw the banner on SO about "Here's how it works" claiming "The best answers are voted up and rise to the top".
That is how I feel it supposed to be, but this is not true.
Not the best answer rises to the top but the answer one person likes is fixed to the top. It does not matter if this answer is the worst possible or even simply wrong. If you look through old questions you will find many questions where the second answer has a lot more votes than the "top" answer. Often this answer is truly better than the accepted.
The top answer is not democratic but a small despotism of the OP. There has already been questions about that but still some people believe the OP is the only one facing a specific problem. While that might be true for the second he answer a question, it is officiously wrong on long term. People face the same problem will google it and up vote what works for them. OP does not know it better as them.
I am not claiming to have a solution but I think the issue should be addressed.
