Yesterday I went to Ignite Seattle again. The event was insanely packed. The room was hot, the crowd was wild and the presentations were far better than the previous instances.
The one thing I must say if you are going to present on the Ask Later sessions (20 slides in 5 minutes), is not to try to cram as much words in 5 minutes, but to deliver the best information about your topic in 5 minutes. Pick just 3 points that you want to get across and build on that. I see the same mistake over and over again, where people try to have 20 slides each with a different content and they try to speak as fast as they can for that content.
