Does anyone has a knowledge of body language to interpret a such hand shake? It's quite tense-Vitalik's wrist is really in an uncomfortable position. How can this happen and what could it mean? Sorry for bringing this woodoo nonsense-just very curious
There might have been several shots to get it right. After a few failures because of the poor-quality camera and the lighting conditions, they might have been trying to hold tight while shaking hands, because they knew it would be a blurred photo otherwise. And that's a bit absurd, not being able to take a photo of two people shaking hands in 2016. So this might be why they seem to have put on a somewhat humorous and/or relieved-enjoyed posture. While Vitalik seems to say "we did it!", holding it tight and not moving, Sasha seems both feeling-the-absurd and at the same time concerned about the awkwardness of the position, but still happy because this time they're going to have a nice, at least not blurred, photo. It also seems that the photo is taken after the panel, because otherwise a tension should've been expected; they're relaxed in a way that only a finished conference could yield such one. Since the photo-taking struggle overtakes their last minutes, there's not so much left from their earlier concerns, so it's quite hard to tell about their feelings towards how the conference really went.
You wanted woodoo, and I'm a relentless speculator : )
