Martin has blogged my conversation with him the other day about liveblogging. For me, the reason liveblogging is of lesser significance ('dead' being a Steve Gillmor-esque abbreviation) is that now events are routinely videoed, the truly important thing is original analysis. 
Also, I find that unless you dose yourself up on caffeine, liveblogging requires a lot of focus. It was a necessity in times gone by. Now, analysis is far more important. I'd rather read a blog post with someone describing a talk they went to which contains some unique analysis of whether or not the speaker is actually right or not. 
I didn't live blog much when I was in Paris for Le Web, but I have liveblogged at events where the video did not come out for months - and a few where it never came out at all. 
The other realization I had was that none of it matters. Who cares about some tech conference? I don't read other people's liveblogging. Why would I want to write something that I find absolutely no value in? Why do we need it live? Think about live television. In the last decade, there has been only one event that has really needed live television - September the 11th. When you watch the news and they have live, outside broadcasts, it's more a clever gimmick. When Britain was flooded last summer, we watched BBC reporters in wellies standing in flooded streets. Yes, it's flooded. Why do we need a live, outside broadcast unit to tell us that? There are those key defining moments - the attacks on the Twin Towers, the death of Princess Di and the inauguration of President Obama - where the rawness and importance of the event is based on it's liveness. Reading notes about a PowerPoint-addled presentation at a conference on social media or Web 2.0 or whatever is not one of them. If it's important, it'll bubble up as video later. 
Which reminds me, I finally got around to reading The Onion's election blog War for the White House today. There's some hilarious personas on there, but Oliver Thayer is my favourite. I'll use this as a teaser: Who needs book knowledge when you have blog knowledge? Heh.
