Conference speakers: Why do you teach at events?

I’ve put up a Twitter poll to find some answers to the question: Why do speakers teach at events? Especially at events where there’s no compensation.

I know more or less why I do this, but I’ll hold off on my answer. I want to hear about you.

#SQLSaturday and other conference speakers: Why (primarily) do you speak at events? For "other", reply to me.
