Are you taking care that if the <link> tag spans over multiple lines (linebreaks in between), you're still parsing it right?

You do seem to be resolving relative paths with:

  feedUrl := matches[1]
  if feedUrl[0] == '/' {
      feedUrl = url + feedUrl
  } else if !strings.HasPrefix(feedUrl, "http") {
      feedUrl = url + "/" + feedUrl
  }

So I think this is good. Just trying to see what could be breaking for the other users who are complaining their feed isn't listed.
