Since I don't have full knowledge of this 'An Old Story' by Jonathan Littell, it might be about an old personal experience. Maybe it's about a family story that has been passed down, full of memories, emotions, and lessons from the past. It could also be related to historical events and how they are remembered and told over time.
The main theme is self - realization and the pursuit of excellence. Jonathan, the seagull, is not satisfied with the ordinary life of his flock. He wants to fly higher and faster, which represents the individual's quest for personal growth and breaking free from the limitations of the group.
Well, the main theme in 'Jonathan Livingston Seagull' is about breaking free from the norm. You see, Jonathan doesn't conform to the typical seagull behavior of just scavenging for food. Instead, he is obsessed with flying and perfecting his flying skills. It's like a metaphor for people who want to break away from the daily grind and reach for something greater, something that fulfills them on a deeper level.
There's no way to really tell if it's common specifically for someone named Jojo. However, in general, reading fanfiction is a popular activity among fans of many different franchises. The Jojo series has a large and dedicated fan base, so it's likely that there are fans named Jojo who partake in reading fanfiction, but we can't say for sure how common it is without more data.
I'm not sure exactly who Jonathan Wamback is without watching the story. He could be an ordinary person with an extraordinary story, or someone well - known in a specific community or field.
Perhaps this Jojo is interested in exploring different interpretations and stories within the Jojo universe that fans have come up with. Fanfiction often takes the existing characters, settings, etc. from the original Jojo series and creates new and unique storylines. So, this Jojo might be a big fan of the series and wants to see what other fans have imagined.
