The author learned several things from audience feedback that surprised them. While they initially believed their target audience would be teenage females based on early feedback, their actual largest audience is males aged 18-24. They were also surprised to find a large middle-aged audience and viewers from countries beyond the UK like the US, Canada, and Russia. However, they were not surprised that most views came from computers and phones, given their broad target age range, or that the UK accounted for 64% of views since the school is located there. The author also expected views to decline after the initial launch due to less promotion over time.
