You only need to do it if who you are talking to is unclear. If you quote someone and are talking to the person who you quoted, then you don't need to address him/her. If you are talking to multiple people in one post, you should address them. You should have a divider using "----" (on a line with nothing else) to show when you are switching to another person if you are speaking to them separately.
