I just noticed that at the beginning of mag 106, Melanie does a clap. I haven't confirmed if she does that in other episodes yet or not, but assuming she does, I love that little nod to her being a youtuber. I remember Tom Scott making a video about the little clap he does at the beginning of his videos, and anyways now I'm imagining the clap is a reflex from her time working with audiovisual medium rather than just audio. I also love the metalevel of a tma character doing a clap to sync audio, while the actor playing said character is surrounded by sound guys who (based on the bloopers) spend a lot of time clicking and clapping to get the audio balance right.
