I don't browse US newspapers that often, but I regularly observe blocked ones, particularly smaller ones. Non-deterministic, e.g.: New York Daily News, Chicago Tribune, Baltimore Sun, Dallas Morning News, Virginian-Pilot. Beyond that, a lot of CA and San Francisco Government and local utility services are geo-restricted (which I think, from a security standpoint, makes at least somewhat sense..).

Btw. asking once is enough ^^
