awesome-lnurl VS lnbook

Coincorner fees aside, this works on an open standard: https://github.com/fiatjaf/awesome-lnurl

What you are looking for is LNURL. Electrum has LNURL not implemented it yet. You find a list of LNURL capable wallets and solutions here: https://github.com/fiatjaf/awesome-lnurl

Awesome things done with lightning's lnurl protocol

Yes use a wallet that supports lnurl-auth. Full list here: https://github.com/fiatjaf/awesome-lnurl

Yes, but sender is not required to use Strike. Also, it's Strike API, not Strike app, but API details are not public, likely you will be able to link your account with other wallets too. With LNURL it should be possible.

I really like all the new things that keep popping up, like Lightning Address, and the lnurl protocol

The lnurl protocol makes things extremely smooth and nice. Also you can use Lightning wallets for authentication, and so many cool things keep popping up all the time, like Lightning Address so that you can setup a payment through lightning to any "internet static identifier" like an email, telegram username, whatever.

This faucet uses one of the new protocols for lightning, lnurl, and it makes the transfer of Bitcoin with Lightning literally as easy as clicking a link.

p.s.: if you're unfamiliar with these terms, I suggest you read the How the Lightning Network works chapter of Mastering The Lightning Network by Andreas Antonopoulos. It's not too technical and if you have a basic understanding of Bitcoin, you won't have any trouble reading it.

Mastering the lightning network

You can read all about it here if you are interested: https://github.com/lnbook/lnbook/blob/develop/12_path_finding.asciidoc

I don't know about videos, but if you want to go technically deep, good start is Mastering Bitcoin (https://github.com/bitcoinbook/bitcoinbook) followed by Mastering the Lightning Network (https://github.com/lnbook/lnbook)

Lnbook getting closer towards being finished and can already be seen at: https://github.com/lnbook/lnbook

No problem. If you want to deep dive into LN, there a free and open-source book here, the first few chapters explain a lot about this without being too technical, and the following one really go deeper: https://github.com/lnbook/lnbook/

I recommend you to read Mastering the Lightning Network, especially this chapter, which explains the basics of how the LN works.
