Thanks for the links.
Deeper investigation shows that your server is returning a 301 Permanent Move message for the feed URL. The feed down-loader in Syndicate Press does not currently handle redirect following. This also explains why the browser followed the redirect, but the SP feed down-loader did not.
Here is the header returned by your server:
HTTP/1.1 301 Moved Permanently Date: Wed, 26 Oct 2011 04:14:01 GMT Server: Apache X-Pingback: http://salamiandeggs.com/xmlrpc.php ETag: "697b18753ce3834e94a6d8633a339bc9" Last-Modified: Tue, 25 Oct 2011 15:18:37 GMT Location: http://salamiandeggs.com/feed/ Content-Length: 0 Connection: close Content-Type: text/html
Over the several years of SP being out in the public release, your sites are the first I have encountered using permanent move of the rss feed. I will look into supporting redirect following in Syndicate Press for a future release.
As a side note, a whois query shows that bobschecter.com is being hosted on godaddy servers. I did a quick google search for "godaddy wordpress 301 redirect rss" and found lots of responses about weird 301 redirects with godaddy hosting. Not to say there is anything wrong with that, but it is curious. I still hope to enable 301 redirect handling in SP, but this at least provides a root cause to the issue.
