Thanks. Yeah, the experience on mobile devices too is admittedly pretty poor right now. I wasn't ready yet for the traffic but I'll get this fixed.
It's not optimized for mobile but I went through it on an iPhone 6s and thought the experience was pretty dang good.
Hmm, odd; works on my machine. iPad Air running iOS 10. Haven't spent a lot of time on the site, and I see the occasional alignment glitch, but a long way from "not usable".
