 ## The solution
 
+Feedburner works by forwarding requests for a feed through
+feedburner's own servers, tracking each person and adding advertising
+as they do so.
+
 Fortunately it is quite easy to defeat the redirects to feedburner.
+Feedburner needs to be able to read the feed properly, so redirects
+are usually set up to let requests which claim to be from 'feedburner'
+through to the original feed.
 
 Firstly though we need to find out which feeds are redirected through

+### Other methods
+
+There are two other ways for feedburner to infect feeds, which are more
+difficult to deal with. These are 'hidden feeds' or subdomain redirects.
+In each case, the real feed location is somewhere else, and the
+advertised location is only served by feedburner. In these cases
+changing the user agent will not work.
+
+Feedburner are also active in podcasting, where they brand themselves
+"podtrac". These podcasts also tend to use subdomain redirects.

+Your only option in this case is either to try to guess the real
+location of the feed, or to ask the site owner directly (depending on
+their disposition, you could make the case against feedburner, or just
+claim that you have problems accessing feedburner's servers.)
+
+## Conclusion
+
+Website owners: respect your readers. Don't sell them out for
+a few pennies a month. If you want to better understand your readers,
+ask them to write to you. If you want to make money, do so in a way
+that is more respectful to your readers and your work than advertising
+and spying.

+Readers: there is a big market in trying to disrupt your life. The
+internet is seen by many as a perfect tool for surveilling and
+consumerising. However it doesn't have to be so. With good information
+and tools, we can keep the internet as a decentralised and free space.
