With the verbiage about dragging videos and a vast expanse of white, I spent a moment wondering whether something had failed to render before I thought to try typing something into Search.
Also: "embed", and don't be afraid to use capitalization.
All that having been said, the densepack display of video thumbs is nice.
You are right. I have a long way to go.
I liked the overall idea. Give the search box a prominent position.
