One thing I don't think that's been brought up yet is the type hierarchy. The "Features" and "FAQ/About" sections seem to suffer from this the most. I find the headers and paragraph blend together a bit too much. Just increasing a bit of spacing here would probably help out.
Also, it looks like in the Features section something is off about the type rendering. At least on Win10 Chrome 59.Edit: Seems to be due to the lack of a proper tag like a < p > for paragraphs or < hX >'s for a heading, right now they're just rendering from < div >'s.
