This affects relatively few people, so isn't a pressing issue.

This is running well and doing the job. WF implementation will be handled in T891.

Just deployed on Write.as, and seems to be running smoothly. The real test will be tonight through tomorrow morning, when we see our normal influx of traffic.

This is more important on Write.as now, especially with replica MySQL databases that have become increasingly laggy.

Internal support for this is finished on Write.as Web, and will be deployed soon.

High-level implementation ideas so far: https://micro.baer.works/working-on-support-for-categories-phabricator-write-as-t809-today

Implementing this should also fix writefreely#219 and writefreely#335.

Is there a ticket for being able to include multiple streams of data on the front page (making it possible to have sections for "All Recent Posts", "Featured Posts", "Posts Tagged with X", etc)?

The refactoring involved here would also fix certain hashtag-related items like WriteFreely #219 Only hashtags with English/ASCII names are supported.

This will likely be a moderate refactor.
