Good point. I guess to be perfectly relevant to me, it would be a mix of technology entrepreneurship and stuff related to that (languages, tools, platforms, etc.) as well as some mind-expanding CS stuff, and finally the kinds of maker projects that one might find on hackaday.
I think what I'd really like though, is not so much the hard-core tech content (audio is not good for that), but just to get good portraits of technically creative minds, their ideas, and their stories.
Hackers focus on the the "how" and "what" of technology, but rarely the "why". The story of the idea itself, and its relation to the creator's life, is left untold. Non-hackers trying to write about technology struggle to find the human story, because they don't really grok what the technology is or what that person's contribution has really been. There's got to be some way to tell these stories.
