Five minutes. Twenty slides. One passion. That's the formula for Ignite Phoenix, a local version of the presentation series originally developed by O'Reilly Media. For each edition of Ignite Phoenix, several would-be presenters submit talks based on their greatest passions. Eighteen speakers are chosen and stand in front of 800 or so audience members at the Scottsdale Center for the Performing Arts. Topics range from "Better Living Through Fast Food" to "Social Media Stole My Kidney!" Just about every Ignite talk is interesting, and if one isn't, another one will be up in only five minutes. Ignite Phoenix has grown a lot since its first incarnation in a tiny conference room at the Jobing.com offices. Tickets sell out quickly. There even are offshoots, such as an ASU-specific Ignite and an Ignite After Hours for topics that are not safe for work. If you need a shot of inspiration, light a fire under your ass and get it to Ignite Phoenix.
