I proposed an idea to speak at Droidcon in New York, so I travelled domestically to speak. The event gave me a free ticket, and I was not paid to speak. The event assisted with part of my travel and accommodation. My employer did not pay my travel expenses, and I took unpaid time off to speak. It took me 1 week to prepare for my 40 minutes speaking slot, and I had a mostly bad time. I'm a woman who has been speaking for 3 years. This was a for profit event. Also, I felt like I did not belong there. Not sure why.
