Subscribing to a subset of a Blogger.com feed
If you want to subscribe to an Atom/RSS feed on a Blogger/Blogspot page but you want just a subset of the content, you can select a custom feed by label. It’s not obvious how to do it though without docs.
For example, I wanted to watch for details on the JBoss Drools blog, but right now I only care about the Planner subproject (http://blog.athico.com/search/label/planner). The whole Drools blog is too verbose for me, so I found the feed URL from view-source (http://blog.athico.com/feeds/posts/default) and I tacked on the “planner” filter (http://blog.athico.com/feeds/posts/default/-/planner).
