Spot on Neil. I don't know what Cory Doctorow's speechmaking income is but for those of us writing fiction we have thing to pay the bills - book sales, and any audio and TV or movie we can get on the side. Comparing novelists to rich businessmen like Anderson or a professional speaker like Doctorow is ridiculous. We're lucky if we get expenses to go and talk at events, not fat appearance fees. That's the reality for everyone, like it or not.
