It's now very easy to pay LN invoices, so easy in fact that there's even an app out on android and that was a huge step.
I ordered a sticker the other day and read articles on yalls.org and it's amazing, if you haven't tried it yet definitely grab a handful of satoshi and try it for yourself.
With that done the bottleneck in public testing has now moved on to accepting payments, it still takes quite a bit of work and technical knowledge to set up a node etc. In fact I'm currently struggling through that myself (new node soon yeay) and I'm not stupid but it's hard and takes considerable effort.
I can't wait until some sort of easier way comes along, maybe even a buffer that takes LN payments and forwards substantial sums to a BTC address.
