What photo sharing platform do you use most?

As I pondered life over a cup of coffee this morning, I thought about how many social media sites I share photos on.  Of course, instagram is on my iPhone so sharing on facebook, twitter, and tumblr has become altogether too easy and I post almost daily on all of them.  Then I asked myself, “Which sites should I be posting on predominantly?” Of course, I then wondered what everyone else used the most.  Do you use flickr?  Instagram?  smugmug?  Please take a moment to take my survey below.  I’d like to know what you use the most.
