I didn't look from mobile, so not what you asked, but here are some first impression comments.
1. Rendered in desktop Firefox I was pleasantly surprised. There was no horizontal scroll bar, everything rendered withing the size of browser that I was using, not one that a designer assumed. So many "busy" sites (lots of UI features and activity) seem to assume full screen browsers. So, nice.
2. Rendered in desktop lynx (a text-only browser) looked like full content and activity was available and sane. I haven't done much on the front end, but when I do I check it in lynx, assuming that if it doesn't suck there then it's probably usable on mobile and in accessible readers.
3. Related to 2, it appears that the order of content displayed in lynx is essentially the same as desktop firefox. You can see counter examples if you look at any advertising-heavy commercial site in lynx; you'll see pages of content that were never meant to be displayed, followed way at the bottom by the actual content. The actual content may or may not be in the same order as the desktop experience.
I think of content ordering as meta-content. You present it in a particular order for a reason. So again, nice job here.
4. I am not a UI or UX professional and I don't know what I'm talking about. This is based purely on what has annoyed me in the past. Your site has very little annoyance for me.
