Please consider the following suggested improvements for article tags.
  1. Display tags on the article page (even optionally)
  2. Provide the ability to see all tags in one place: /tags
  3. Provide a listing for each tag that shows articles that have been tagged. Should be accessible from the list in #2: /tags/tagname
  4. Improve documentation on tags. Currently, all I can find is a paragraph on the article settings page ( and it's very vague ("You can add upto, say, 5 tags for an article." <-- what does that mean? Is 5 the limit?)
  5. Maybe consider changing the name from "tags" to "labels" or "keywords" to help distinguish the difference in your documentation. Searching for "tag" brings up a lot of things about HTML and CSS. Just a thought.
