> What is blocking its adoption?

There's no native web experience that makes it easy to use Lightning in a browser; this forces everyone to step outside the box to figure out a way to (e.g. install extension or download an app)

There's also not much of an app ecosystem for it providing enough utility for people to use it each week/day

Interesting, so this is I believe the same problem as all the Ethereum type stuff: you need to have it lives with your keys in the most horrific place in a computer, meaning a browser extension. Or put the web browser in the wallet. Either way, something like Metamask is really slow and scary.

The core Ethereum stuff is pretty elegant but once you want to build an UI you get trapped in hell to plug it to the "web".

Maybe the biggest problem of "Web3" is it was built on Web2.
