Does anyone know anything about Solid pods?

I heard about this project years ago. Cool concept: standardized, interchangeable storage + identity that can be plugged into arbitrary apps. The idea is that your identity is tied to your data, and your data can be hosted anywhere so you can retain control over your data or use a simple provider. It was also created by Tim Berners-Lee, creator of the web.

However, it doesn't seem to be gaining traction anywhere, even in the already-niche self-hosting community. From the GitHub (which was hard to find on the website!) I could see that it's being actively developed, including a new website redesign, but everything else seems stagnant. Their newsletter has no updates since 2021. There are only a small handful of apps listed on the site and most of them haven't been maintained since 2019 or earlier, and a lot are just things like "solid pod explorer" or "demo app".

Anyone had any experience with it? Or know more about the situation? I would love to see this become more widely used.
