I wholeheartedly second his suggestion and want to encourage you to take it a step further. If your city doesn't have it's own Ignite event, be the one in your community to start it. With the help of O'Reilly's guide and some planning, it's not difficult and is an excellent way to bring your community together to discuss interesting ideas and, possibly, raise a little money for a good cause.
For example, Ignite for a Better Baltimore was recently held to bring together Baltimore's social enterprise community and featured 16 speakers who are working to change the community for the better. Money received from ticket sales will fund an Ignition Grant. Videos from this event are available online.
(I'll admit I'm horribly biased about the Ignite for a Better Baltimore event. Together with Alex Rinsler and the support of Mike Subelsky and Heather Sarkissian, the people behind Ignite Baltimore, I helped coordinate this event.)
Skeptical about starting up an Ignite event or need a few ideas? What about having an Ignite event at a bar association conference and invite people to speak about their pro bono practice? Or have a training event that has family law experts talk about the law or share moments from their practice? - K
