I think that part of the problem is that being able to design something doesn't always mean that you're going to feel comfortable or personable talking to thousands of people on camera to Twitch/YouTube/Nico. Yoshi/Foxclon have been doing this for years so they can discuss the subject matter comfortably while being entertaining at the same time. When you think about how long some of these Live Letters go on for (upwards of 4+ hours), it's probably an incredibly stressful experience and I'm sure that they'd love to have someone equivalently charismatic and knowledgeable on the subject matter stand up and talk instead. But they're eventually going to have to train up more of their team members to sit in front of a camera.

What I would like to see them eventually do is actually make use of their channels and host more frequent, more focused, and shorter segments on topics of interest, be it job design philosophy and current balance issues, housing/glamour stuff, or whatever. That way you can tune in to the stuff that you're interested in, rather than wading through a lot of fluff to get there. Even if they did it in something like an interview/Q+A format it would work, because then really only the show host has to be a good conversationalist. Even a podcast might be nice if it's a less intimidating format.
