Kind of proud of this... I just finished per-topic browsing on @readwriteas, and instead of creating new database tables and adding to the admin UI, I just stored the featured topics in a plain Write.as post (https://write.as/w9fggtfchntbfj6c.md). The server uses the go-writeas library to fetch the post, does some simple string operations, and then generates the navigation bar.
What do you call this? Bootstrapping features on the platform I'm storing data for the features on?
