I'm having the same problem, I can subscribe to some SSC RSS feeds in Google Reader without a problem, but others just show up as 'Permission Denied."

The only difference I can see is that the ones tht work have a number under a 1000, and the ones that don't are over 1000.

this works: http://www.sqlservercentral.com/Forums/RssFeed391-0-0-1.aspx

this does not: http://www.sqlservercentral.com/Forums/RssFeed1044-0-0-1.aspx

I don't know if the problem is on the SSC or Google Reader side. Any ideas?
