People too often talk about “The Fediverse version of X”, or “Add ActivityPub to X” without actually talking about the point of it, or what the functionality would be. It’s discussed like a badge that says “I did Fediverse to it”. I wish people discussed this kind of thing from the feature level first. What is it you want to do? What would federation offer you? Does that even make sense for that product? Just saying “Fediverse version of the Chase credit card app” sounds great, but what would that even mean? Is that something people need, or do you just want more “Fediverse stuff”?
I often get requests for random Federated ideas with Owncast that sound cool, but don’t truly solve a problem people have. Identify a problem, come up with useful functionality, work backwards from there.
