No, a tag cloud is not a meteorological phenomenon. Nor is it a children’s game. In order to really understand tag clouds, we first need to understand tags. Tagging is a way to label, categorize, archive and find things on the internet. For example, you might tag a collection of photos on a photo sharing site with the word “Amsterdam”. You would then be able to find themt, and associated photos with the tag “Amsterdam” more easily the next time you visit that site. Sometimes tags are automatically generated by the Website’s software based on the number of times particular words are used in an article or other piece of content.
