The woman making the video says she likes to look for patterns. (I like to look for patterns as well, because they teach me things.) But she only focuses on one type of pattern: people who don't respond to posts. She gives no comparison patterns to show that this woman's pattern is different to other people's patterns. How many regular posters on here don't respond to the comments they get? Quite a few. It's just their nature to not respond because it takes up time. Other people like to respond because they have the time and/or like the attention/discussion/whatever. We all have different patterns to how we deal with online posting.
