I think if they stayed on one client like Amethyst, it is easy to scale, but to utilize other apps in the ecosystem a lot of it needs work when it comes to interoperability. Let's say I started a podcast, and I am on Fountain. It is hard for me to bring my keys over there from my extension/key signer, so I have to create a new account (which I did; and not wanted to plug my keys into everything). It's still early and everything feels scattered... this is from a non-technical person's point of view
