I proposed an idea to speak at Droidcon NYC 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 did not pay for my travel and accommodation. My employer paid all of my travel expenses, and I used my PTO to speak. It took me 4 days to prepare for my 45 minutes speaking slot, and I had a great time. I'm a man who has been speaking for 0 years. This was a for profit event.
