I also do quite a bit of writing, but the videos are a nice change of pace. A few people have suggested transcribing the videos - and I'll look into doing that. I realize video isn't an optimal medium for everyone.

I actually found it refreshing to see a human face instead of just text.

I watched about five seconds of jerky video, barely audible over the fan of my aging MacBook.

I've seen several video presentations come up on YCombinator. It makes me wish that embedded players had could be sped up like VLC. Given a typical presentation, you can watch at 1.5x with no problem.
