I'm an ESDF guy and move forward with mouse button 2. I think it makes more sense as you get more keys to bind within easy reach. But to each their own. People should use whatever they're comfortable with.
...but it makes Ctrl / Shift quite a stretch and leave my pinky over the Windows key(!) - very bad for gaming.
I popped the Windows key off my keyboard, melted it with a lighter and gave it to my brother to place on top of his Mac with his other nick-knacks.
