I was watching Defcon Unlocked Presentations and was inspired to blog about it.
The conversation centered around new people and especially women and minorities who feel like their message or their voice is unsuited for public consumption, especially at large conference venues. Many people who I greatly respect weighed in on this topic, and I'd recommend it for watching. This is my take.
Know your message. Cater to an audience. You're not an imposter. Inspire people. Take it seriously. Don't be afraid of failure. Know your support. Design with intent. Presenting is a skill.
