Tagging is a popular method of classifying and organizing entries. Tags are simple, comma separated words or phrases that you attach to an item which describe particular facets of it. Tags provide extra metadata that can be used later to find a particular entry or other entries like it within the system. Tags are most effective when they are very specific. This specificity is gained through the use of tag combinations, which essentially form “tag intersections.” Tags can optionally be displayed on the published weblog where readers can click on them to find other entries that are similarly tagged.
