Re the blogginhead TV format...I agree, I never watch them. I just don't like the medium. But I also agree with you, Glenn, that it gives an opportunity for immediate back and forth. Why can't this happen, though, in a blog format? Have a blogginghead blog where two bloggers are invited to participate in a back and forth, make some expectation about how quickly each one must respond to each other, etc. Slate does this sort of thing occasionally (Dahlia Lithwich and Walter Dellinger, for example, usually do a back-and-forth about the Supreme Court at the end of term), the only thing is, the responses are usually like one or maybe two a day. But if you had a commitment to a faster response time, it might make for some interesting back and forth. Just without the tv.
