The "don't know it exists" part is the real problem to solve.
Nobody gets converted by "Lightning is fast and cheap." They get converted by using it to solve something they actually care about.
For me it was spam. I built an email system where strangers pay a Lightning invoice to reach your inbox. You either pay or your email waits. Spam dies not because of filters, but because of economics.
People don't need to learn about Lightning. They need a reason to open a wallet.
