Great design & feature set.

Feedback: the navigation bar at the top is quite unusable from an UE point of view. The positions of the icons (and therefore the hovering position) change as the mouse hovers them. It is quite annoying.

Also, in the FAQ: "How can this be a free service? Magic" This sounds to me as: "stfu, don't ask, you are not clever enough to understand" or "there is some dirty way to get money from you, better don't ask".
