First Tag Wiki Edit. Ask Ubuntu has tags that split questions into different groups. These tags allow the site to remain organized and help users by allowing them to subscribe to or ignore topics they might find interesting or wish to ignore. Each tag has an associated wiki page called a tag wiki. This page describes the tag, how it's used on the site, and anything the community might find useful about that topic. It is the bridge for that subject between Ask Ubuntu and other canonical references to the subject on the internet. The ideal tag wiki contains many links to other resources.
