Yeah, so this is a pretty good lesson. The internet is filled with "haters" and a lot of people will criticize almost anything anybody writes. If the comments are negative and don't provide value or are rude, your best bet is to simply ignore. People will talk and comment as if they know everything (this comment included), so it can often feel very aggressive. Respond and form relationships with your commenters who are positive and provide constructive criticism. Good article. Ignore the haters.
