Check out Daniela Barbosa‘s beautiful (and free!) ebook, Taxonomy Folksonomy Cookbook! She introduces the subjects of taxonomies and folksonomies, and encourages you to use both in your recipes. It does include a pitch for Dow Jones, Daniela’s employer, but it’s low key. Regular readers know that I’m no fan of advertorials, and I’ll vouch for the legitimacy of the content.
