Your free to modify the code but we have found that most shows with multiple links to their RSS feed on their home page that nofollow has proven to be an optimal thing to employ in this specific instance. Otherwise some shows could have 10-15 links to their rss feed on their sites home page while generally not an issue we have seen shows be hurt in Google making it appear they are trying to over emphasize the feed and causing it to be depreciated.
