@tante @Ihazchaos Part of me believes that it should indeed by a competition. I personally believe that bluesky corp has bad motives, questionable leadership, and a harmful business model that among other things creates an ecosystem that will be heavily controlled and restricted and not open to the many like fedi is.
But part of me recognizes that actual decentralization which the fedi is and the bluesky is not, and might not ever be, creates a different experience than the entertainment broadcast that many big "social" media apps have become.
There is plenty of shitposting here on fedi and even inside joke memes about those shitposts, but it is not being shared to random people without people's consent. If one joins fedi at at the beginning of adulthood and joins a friend of a friends server the fedi I would gather the fedi would feel a lot more like shitposting space. If you join the fedi through a professional network, your posts will indeed be majority ones of the professional variety.
Regardless of whether the fedi and bluesky should compete, I definitely think there is need for more tools to share posts of a different variety and tools to fetch those varieties; this would help people get more diverse timelines. Akkoma makes some strides in this direction with admins being able to to create a "bubble timeline" (of different local servers timelines) to share with users of their instance. Calckey through the use of antennas allows each individual to create multiple personal private bubble timelines. Federated groups(like friendica has) also has some potential.
