A tag is a type of metadata keyword or label which makes it easier for you to find posts within this blook on a specific subject or term. It’s a little bit like a regular book index.
The tag cloud shown above is a visual representation of all the tags associated with the posts in this blook and are listed in alphabetical order.
The larger the size of the text representing the tag the more frequently it appears in the blook. Each tag is hyperlinked to the posts associated with that term.
This format is useful for quickly viewing and finding the most prominent subjects in the blook.
