I'm using Firefox and there are actually many usability issues, which I only noticed when I opened the same page in Chrome. The bigDot's are too large and cover some of the text. The venue map doesn't show up on Firefox at all. Circles next to About/Speakers/Schedule/Location overlap each other. And so on.
