Blogger Category Posts

Blogger publish ATOM feed for recent posts by default, including posts from all categories.
To publish a feed with only posts from a given category is also very simple. For example, in a blogger site http://blog.lizhao.net/ with category named 'maemo', the feed is:
http://blog.lizhao.net/feeds/posts/default/-/maemo
