1. It helps to have at least two people to cover things with text, audio, and video. The more, the merrier. Liveblogging is difficult unless you're a world-class typist. One person can type the main points of the proceedings, another can take photos and insert them into the posts, and another can take audio. (And another can do live interviews, etc.) At any rate, it's good to divide up the responsibilities. Tim created many of the entries and entered some basic information that I was able to then build upon as I typed up notes according to what was said.
2. Wouldn't it be nice to make a conference wiki and enlist the help of conference attendees in preserving an excellent record of the event? If you have any experience doing that, let me know.
3. I think we'll start seeing more and more conferences - no matter what they are about - done completely (or at least in large measure) online. Why force everyone to leg it all the way to a unified physical location if the costs of travel could be applied to publicizing, executing and reviewing the conference itself instead?
I think that instant publishing of a conference in an inexpensive, easily searchable and even editable manner is a fascinating thing. Let me know what thoughts or tips you have on how to cover a conference using blogging and other quick publishing methods.
