## Overview
We should provide a topic / subject tagging mechanism, through hashtags. Users should generally insert them anywhere in their posts.
## Implementation
We already parse out tags for posts. We should store these in a `tags` table and make tagged posts accessible on users' blogs at write.as/{name}/tags/{tag}.
> **Known issues**
> Right now, any **hashed part of a URL**, especially when pasted or used as a link in Markdown, gets extracted as a tag.
## Design
Tags should be parsed on the server side, and the HTML served with special `<span>` and `<a>` tags that make the pound symbol more transparent, but link to the above blog tags URL.
