## Overview
Blogs should have a page that lists all tags that have been used on that blog.
## Background
Users want a single place to come to and browse all the topics they've written about.
### Users
Suggested by Connor Martin [on the public roadmap](https://trello.com/c/a33P6cug/36-organize-posts-with-tags#comment-5a202bfcc9f59c6e33d1902f)
## Implementation
Whenever a user publishes, updates, or deletes a post, update a table of data with all used tags.
| tag | canonical_tag | collection_id | user_id | post_id |
then `SELECT tag FROM tags WHERE collection_id = 1` and display them all on a page.
