## Overview
Support viewing all posts on a blog with a specific language.
## Background
Blog authors should be able to have e.g. both an English and Spanish home page.
## Implementation
Similar to when viewing hashtags, filter posts by stored language on this URL: e.g. `/lang:es` where `es` is the language code.
### Design
The page should look exactly like the standard blog index page, but only containing the filtered posts.
