I proposed an idea to speak at Open Source & Feelings in Seattle, so I travelled domestically to speak. The event gave me a free ticket, and I was paid 500 USD to speak. The event did not pay for my travel and accommodation. It took me 2 weeks to prepare for my 15 minutes speaking slot, and I had a great time. I'm a person who has been speaking for 1 year. Also, They sent me check well in advance so I can use honorarium to cover travel expense.
