David Gaughran has a good post on a service designed to help agents rip off writers. In a delicious irony, agents who sign clients onto this service will hasten their descent into bankruptcy, because as Gaughran's post makes clear, they obviously doesn't know a damned thing about actually selling books--they don't even use categories correctly! Honestly, the most serious problem facing traditional publishing today is that the people in it so clearly believe their own bullshit.
And Lindsay Buroker has a good interview with a lawyer specialising in literary and publishing law. I especially liked the story about the agent who would advise you on whether or not to sign an agreement with him. I'm sure that's some totally unbiased advice being offered there....
