I'd only say I fit none of these descriptions in the poll, so would not answer it.
Highly experienced Unity user.
Experienced in another engine/platform, just started with Unity.
Not used any other platforms, but quite experienced in Unity.
Just learning Unity and 2D Toolkit together
It would be fairer to have a middling "Quite experienced in Unity, experienced in other platforms" scenario for a new user to indicate, which is at least many of us, who aren't "Highly experienced in Unity"?
