There's nothing magical about an hour. Volunteers to do other things are welcomed.
I personally think an hour is way too long for a standard talk. Most conferences seem to go for 25min + 5m questions and change over. I really like the idea of a session of rapid fire short talks. Some conferences have an "outrageous opinions" session structured like that. We could have a session of 5-10 min anything goes talks. Give an idea, an experience, a spoof, anything you want the audience to hear. The only rules being sit down after 10 min and wear the flak for anything you say yourself. But, all things are possible at this stage. If think you're interested in giving a talk, let us know what you'd like to talk on and for how long. No commitment needed at this stage, just ideas. Also if you'd like a topic to be covered either as a talk or a tutorial, let us know that too. Any feedback is useful at this stage. Tony
