With the increase in user-generated content (blog posts, comments, photos), disparate data silos, and file formats, information architects and taxonomists will be required to allow users the ability to tag (classify) the data or content. For example, if a vice-president makes a blog post, this post could be tagged with her/his name, title, and the subject of the post. Tagging makes it easier for users of the intranet to find the content they are interested in. This will ultimately cause a ripple effect where users will also be generating ad hoc navigation and information flows. Corporate portals also offer customers and employees self-service opportunities.
