I'm glad I'm not applying this time.
Never mind the irritation of figuring out how to create a video (I'm sure it's easy, but why spend time figuring that out when I could be hacking?) -- I simply don't video well, especially in artificial-seeming situations. And I don't think a video would tell you anything useful about me anyway; my most natural voice is the written voice, so that's what you should listen to if you want to learn anything about me.
I can see a couple of potential advantages to requiring an introductory video -- first, it allows you to detect some fraudulent applications; and second, it raises the bar for entry, thus removing some of the less serious applications -- but my impression from everything I've read here is that neither of those are particularly problematic even without videos. I'll admit that some people speak better in video than in writing -- although I think this applies more often to business people than to hackers -- but surely the right solution to deal with such people is to make an introductory video optional, not to make it mandatory. I know there's a lot you can see when you engage a candidate in conversation which you can't see on a written page; but a unilateral video doesn't tell you how well someone can carry on a bilateral or multilateral conversation either.
I'm sure you guys have some reason for this... but I certainly can't see it. Why?
