Ghost written comments
I’ve seen this done a bit on youtube, sometimes it works, sometimes it doesn’t. The idea is that you make a throwaway youtube account for a character who appears in the clip. This gives commenters a unique perspective for jokes, and it’s fresh enough to give other civilian commenters something to like.
I love stuff like this, usually because the people behind these impersonated accounts can write. Twitter is usually the preferred outlet for this stuff; compared with youtube comments that might struggle to reach the top comments, if a funny @ handle gets some publicity it can stay popular for years. My favourite twitter handle of the moment is Self-aware Roomba, the world through the eyes of a vacuum cleaner learning to think. In response to a home intruder threatening Roomba’s family: “ROOMBA and other ROOMBA know what must be done.” I had fun at Uni writing the twitter feed of a cat that leaves the house at night. I think it’s a valuable writing exercise to think like a fictional character, 140 characters at a time.
