Very interesting blog piece from Charles Boyle here, on the current debate about literary festivals paying (and not paying) writers. It is, of course, a very complicated subject. I'd guess many writers find it difficult to say no to unpaid readings and appearances even if they do feel strongly that they should be paid, but equally I'm not sure if any of the festivals are making a great deal of money out of the whole thing. One to discuss at length.
There's another interesting take on the issue here.
