Overall, I really had a great time. It was the largest skeptics event ever (800 people), but still small enough to meet every speaker personally, and learn a lot. The largest podcasts, Skepticality, and the Skeptics Guide to the universe, were there, as well as CNN, the Las Vegas newspapers and television stations also. There's a lot of smart people in this group, that's for sure. The speakers were definitely hit and miss (who knew the editor of the Onion could be such a boring speaker?), but this event is really "amazing". Don't miss it if you are in Vegas next June (they moved it to the hot Vegas summer so more teachers can attend). Plus, where else do you see t-shirts like this?
