There has been a lot of talks about the new linking pulicy of National Public Radio:

Linking to or framing of any material on this site without the prior written consent of NPR is prohibited.
Please use this form to request permission to link to npr.org and its related sites.

They announced that policy was originally intended to maintain NPR.s commitment to independent, noncommercial journalism. Wired: The fact that some folks still don't understand that if you don't want to be linked you shouldn't be on the Web.
NPR, is one of the few radio stations I ever listen to while driving, and the only station producing useful content (you may have seen some articles here regarding their stuff). The new policy prevents webloggers put any link of any sort to NPR web pages. The policy may have been in place as early as March 2002 or before, but is just now facing the scrutiny of Web citizens as the number of links to NPR grows through the bloggers community. On the other hand, Yahoo! and Google, two of the most popular web portals use NPR material in their news pages, NPR's spokesmen have said they have an underwriting relationship with Yahoo! but nothing was said regarding the links coming from Google.
Who can monitor these links anyways? Do they have the resources to do that? A company spending more than $122 million in 2000 and they want to dedicate resource to monitor the links?!..
