Tags, as I explained in my previous post (Social Bookmarking – Del.icio.us) are keywords or labels that are related to the given topic. They are used for identifying the topic for things like search engines or favorites lists. Many people contribute to the construction of a tag cloud, and the more common tags are shown in a larger font. This is called weighting tags. A tag cloud is a visual of the tags on a website, showing those more common in a larger font, and those less prominent or smaller details in a smaller font (see above image.) The larger words are usually more general, and the smaller words are more specific. Tag Clouds are becoming more popular, with the help of sites like Del.icio.us and Technorati, and Flikr which uses tags for pictures.
