I'm the lead dev at adultempire.com and just finished enabling lighting on checkout. Kind of excited about it and didn't have anyone to tell... at least no one who understands what that means.
Nice ;) Will there ever be statistics on how many people are buying through Lightning Network?
Probably not officially. I can tell you we've had a few people use it in the week its been up... ~ 0.01% of on-line orders, but at least that's a start!
To frame it in a brighter light, about 40% of BTC payments last week were on LN! ;-}
