A system to create tags for tag cloud displays includes an authentication service to authenticate a user. The system includes a set of valid resources stored in a database system. A tag creation tool permits the authenticated user to create at least one tag that serves to identify a selected resource within the set of valid resources. Each tag includes a weighted value. Each tag may include a public attribute that indicates that the tag is accessible to authenticated users and non-authenticated users. Alternatively, each tag may include a private attribute that indicates that the tag is only accessible to the authenticated user. A user interface displays tags in a tag cloud in accordance with attributes of the tags and weighted values of the tags.
