Potential of Cardstack

Hi all,

I think only a few people know the project “Cardstack”. Cardstack provides an out-of-the-box user experience, which allows users and developers alike to construct sophisticated applications and workflows, using common building blocks that are integrated into the platform. Of cours, everything is decentralized and the code is open source.
Here is the website of the project:https://cardstack.com/
I would like to know other opinions about their development and what they could achieve in the future. Maybe @ivan could read about the project and judge it, whether he sees an opportunity here, because they have a nice use case which a lot of people will use.
At first sight the project seems very promising(Of course long term!!!)
