Reader Dave Stephens posted a long reply to my “Tapping Into the Cosmic Internet” entry, and asked questions that were sufficiently interesting that I asked, and got, his permission to post them here as a separate post, since not everybody reads the comments people send.
I started to reply, then realized that I didn’t know what to say. Of course, the obvious answer was to let the guys speak for themselves, so that’s what I will do, with my initial comments inserted within brackets [like this], and theirs at the end.
