I stumbled across this while trying to read some RSS feeds the other day from the recently tightly locked down VSEA interweb.
This is a great program, and even though most of the RSS feeds were blocked by the VSEA hellhounds, I found an interesting way of avoiding them.
Step 1: Google with site:
inurl:xml (or rss, depending on the site)
Step 2: Right click and choose Copy Link Location
Step 3: Paste the link into the Feed URL of Google Reader's subscribe panel
You should notice that instead of www.site.com/feed.xml it pastes in a lot of wierd shit. This wierd shit is the trick, its a link to the Google cache (I assume) of the feed you're trying to view. While it may result in a delay in new feed items showing up, it completely bypasses my corporate web-nazi.
The above works with FireFox, if you don't have it: GET IT!
