I've been in fandoms for 6 years. This community has formed part (perhaps most) of my identity, so when I saw this particular one, about TV series fandoms, in the list of proposed course topics, I chose it without much hesitation. Sitting on Twitter for 6 years is also an interesting experience, so I wanted to use it in scientific work right away. Well, when this is your first experience in writing a scientific work, in any case, you choose what, at least, will be interesting and comfortable to write, if I may say so. I am very glad that I chose this particular topic, because now I have not only personal experience, but also most of what is happening in fandoms and online communities I can empirically confirm, in fact, with my own research.
