I feel a little sad that you felt you had to send a video to demonstrate passion. Don't get me wrong, I'm not saying it was the wrong thing to do and it does show you're making a serious effort, but your talk should stand up on it's own merit. FWIW A talk on how to use vi like a pro I would expect to be well received at a developer focused conference. If I was there I'd certainly attend the talk and no doubt I'd learn a lot. We have submissions where the passion comes across in the content - in fact we've had some where people have said they really want to come and hang out at the con and this is the easiest way for them to do it (as we cover airfare and accommodation).
