TechEd 2006 is a blast already. I've only managed to get to one session so far - Paul Andrew on Workflow Foundation (checkout the article on Paul in Computer World) - but everyone is in a great mood and things seem to be working really well.
This is the biggest TechEd ever - about 2200 attendees plus loads of presenters, sponsors, partners and other assorted klingons :]. It was a little tight for room after the keynote when everyone flooded out of the room at the same time, but otherwise, it's not too cramped.
The Hands on Labs - where I am spending most of my time - are working really well. We had the room three quarters full yesturday afternoon and today there has been a steady stream of people filling in time between sessions etc. There's some really great labs to do to - eg, the ones on LINQ and ADO 3, and Workflow Foundation.
The yellow Intergen shirts certainly get peoples attention, especially when we travel in herds! I'm a bit scared of travelling alone though in case I get picked on. (I'll post a photo as soon as I get a mo).
If your missing out on all the fun of TechEd because you couldn't get tickets then take a look at http://www.techedlive.co.nz/ for a live feed of news and activities.
