The best answer alerts come after the thread generator chooses our reply as the best. More than one answer can be selected as the best answer for a single thread by its author. There would be a bias in selection as it is done by the primary author, the bias would be in the form of personal, topic views, argumentative replies, and language that can be perceived by the chooser as challenging. I choose based on the content, the relevance of the reply, I'm happy if people speak out of experience in life or reply the opposite of what I would expect and substantiate their replies.'I ignore replies when it sounds personal or starts with Don' t interfere, Don't opine or who are you to question, It would be nice to have at least 5 replies that are practical and meaningful. I also like some very brief 2-3 point answer if it is to the point of the thread.
