AP apparently hassled the Drudge Report (also not a smart move) for linking to their stories along with short quotations via reader submissions.
Drudge Retort is doing nothing different than what Digg, TechMeme, Mixx and dozens of other sites do.
AP does not want people quoting their stories, despite the fact that such activity very clearly falls within the fair use exception to copyright law. They claim that the activity is an infringement.
A.P. vice president Jim Kennedy says they will issue guidelines telling bloggers what is acceptable and what isn’t, over and above what the law says is acceptable. They will “attempt to define clear standards as to how much of its articles and broadcasts bloggers and Web sites can excerpt without infringing on The A.P.’s copyright.”
Those that disregard the guidelines risk being sued by the A.P., despite the fact that such use may fall under the concept of fair use.
It's just a bad move by an organization that seems not to understand how journalism is changing.
