I found a very cool short PDF via Kevin Kelly - I didn't even know he had a blog so I'm pleased to have found Mr Wired.
The 6 page document, Tips for Conference Bloggers is by Bruno Giussani and Ethan Zuckerman is very cool. and even in the era of Twitter explosion, conference blogging still has a place.
I'm sure guys like Mike Butcher and Tom Raftery could add to it with their tips. .
It's ok but it's a bit old hat ("don't sit near the front or you will disturb people with your typing" - these days a lot of the rest of the audience will also be blogging!). And if they are annoyed - stuff'em, I've got deadlines to meet.
time for you to write a better one then Mike :P
Just common tips. Everybody knows about these tips naturally.
