I found this quite interesting and also quite savvy - in a world where personal brand is so important, doing this pre-Olympics is a good move. Plus, I love to be nosy and so I enjoy all the ice dance girlies who make vlogs! For a younger audience, I actually think this will do more to grow the audience as opposed to terrible RD themes. Knowing the athletes and rooting for them brings in viewers. That's why the likes of Drive to Survive worked - humanise your athletes, give fans something to support or something to get behind or a rivalry to choose a side in and an increase in viewers will follow.
On another note - I was also surprised at how surprised Olivia was about Adrian's retirement. Obviously we don't know what goes on behind closed doors but as someone from the outside looking in, his retirement was imminent. Especially because of the way that Madison was so open about retiring and wanting to get married and hinted at starting a family.
