I would like to use the <category> tag on my rss feed, but I want to make sure im using it properly. Ive been doing alot of reading that talks about using a taxonomy. But after reading douzens and douzens of pages on the topic, I found no help or example on how to use/create one. Does anyone have any example on how to create and use a taxonomy? I am better off using an existing one? What are some popular ones and how do i use them? My main goal is to use the <category> tag to sort the output in my flash widget. For example, I would like to only display the feeds that have the category 'healthy living'.
