There are many steps to write a quality comment. The first step is to comment something very specific so you, and the author, can relate to something you enjoy. Relating is a good way to start a conversation. The next step is to add something relating to the topic. Adding and relating to something is the best way to socialize with someone. The final step is to ask a question relating to the topic. Asking a question is the best way to keep the conversation going. One bonus step is to always, always, check your spelling, capitalization, and punctuation. And those are the steps to write a quality comment.
