Check out wistia... it is analytics for video. You can actually see how many people stayed to the end. Or if people leave do they leave at the same moment etc. Can be very useful
I wonder if it's just a coincidence that http://jessicamah.com/ is offline at the moment?
Is the video jittery and crazy for anyone else? This is hard to watch.
I noticed it jittered like hell on my phone, while viewing it on my laptop it still jitters, but only slightly. Might be rendering issues due to high resolution video being decoded ?
