This is the talk I presented at the Ubelly Ignite event: http://www.ubelly.com/2012/02/ignite-ubelly-speaker-line-up-announced/ It followed the classic ignite format. 5 minute talk, with 20 slides, auto advancing every 15 seconds. You can find out more here: http://chriswharton.me/2012/04/ubelly-ignite-talk/ Sadly, there was a problem with the video so I am presenting online.
