Consuming a list via RSS can be a very powerful mechanism, but only if users of a site know that it is there to consume. Take advantage of modern browsers' RSS awareness by adding link statements to your master page or page layout. This allows any number of nested list feeds to be exposed at the optimal site level.

<link rel="alternate" type="application/rss+xml" title="[yourfeedtitle]" href="http://[yourservername]/[yoursitename]/_layouts/listfeed.aspx?List={0EA36119-4B12-4292-B6E6-A15B11212A3F}" />
