This is partly in reference to Senior Members Stealing Answers and Out-voting
Sometimes when posting answer on Stackoveflow I find my self posting same answer as someone else at almost exactly same time. Previously when I would notice that '1 New Answer' appeared I would check the answer first and than discard my answer if i found it to be duplicate. If that answer was different from mine I would finish writing my answer.
My own solution: After reading responses to this question and answers on some of the links that were submitted I have decided to follow advice from @kate-gregory to finish writing my answer without paying attention to new answer that might pop up. Once I post my answer if I find it to be very similar I try to improve or reword it to be a better answer.
PS. Therefore I'm no longer asking for a reason to stop me from answering.
