I observed that the folks on Twitter are using LN for payments. LN transactions are super speedy! I tried it once, and boy, it was as fast as using a QR Code linked to a local banking service.

But, honestly, I haven't delved deeper into it. Is this LN network a good idea to uphold the fundamental principles of Bitcoin?
Should all Bitcoin users worldwide embrace LN for everyone to conveniently use Bitcoin as a payment tool?
