My first urge was to reply "Why not?". If you're capable of seeing with both eyes, then why would you want to view the world with only one? That is 2D, but we live in a 3D world. To me, 3D makes almost any image more interesting, but the images must be done very well. I've been learning and developing my 3D skills for 4 years now and still finding ways to improve. I have nearly 11 thousand images on my photostream and only fairly re cently have I started including some 2D. I think there is a place for all formats (if one is open minded), and I enjoy variety with anything connected to life.
