Folks, just to chime in here. This isn't an idle threat being made by a few newspapers. They're basically turning over their copyright infringement enforcement to Righthaven.com. Righthaven is taking an RIAA type stance on this and absolutely hammering the owner of any site where if finds infringement. ANY site. We're not talking about DMCA take down requests - nope, straight to a copyright infringement suit for $75,000 - $150,000 per instance of infringement.
For more info see:
One of many articles by the LV Sun about the suits. Check the one where a 70 year old retired Navy vet got nailed for posting an article on what looks to be his personal (but publicly accessible) blog.
