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 was working while speaking at the event. It took me 1 month to prepare for my 40 minutes speaking slot, and I had a great time. I'm a woman who has been speaking for 3 years. This was a for profit event. Also, I gave the keynote and at the time was working for a corporation. I didn't ask for a fee or for expenses since my employer had me covered.
