Yes, there’s an ecosystem, but it’s neither extensive nor mainstream. Feed readers are hit or miss, and I haven’t found one I like. Subscribing to 50 people is enough to make the feed unusable since there’s little to no organization.
While this isn’t entirely the protocol’s fault, its poor state is largely due to its lack of mainstream adoption—too few people care about it. The protocol itself might also be part of the problem.
So discoverability is still a problem because not enough people care about the existing solutions.
