2nd Logo (June 14, 2011-February 15, 2012)
Logo: On a blue background, there is a burst that emits light from left to right while multiple color-changing light particles flying around.

The "Q" has an orange light burst before it and the particles fade out, leaving the "Q?" with simply a small glow.
