2.2 And at the Other End

No one wants to read raw RSS: the end user will always do something with a feed before consuming it. For the original use of RSS, to provide headlines on another site, this means using the RSS feed as input to an end user's parsing system, which will transform the RSS into something more readable. For example, the Meerkat system will transform the following RSS:

<?xml version="1.0"?>
<rss version="0.91">
