It's not at all scary for me, but it totally would be for a complete noob. It seems really good for someone who's been using a custodial wallet, but shies away from running a self-hosted start9 Alby hub.
It really shouldn't require an "experienced user". I'd say it requires enough technical sophistication to look at this page and not be terrified: https://rizful.com/get_on_nostr_today

it's definitely a step down in complexity to a self-hosted start9 node. Many self-hosted lightning nodes are problematic because the protocol really wants an always-on and very reliable internet connection: https://docs.megalithic.me/lightning-user-vs-lightning-runner/the-lightning-node-is-an-internet-application
Yeah, I have two channels and one is actually to megalithic. My node is just running at home, but it's obviously not as reliable as a data center.
