Software engineers go crazy for the most ridiculous things. We like to think that we’re hyper-rational, but when we have to choose a technology, we end up in a kind of frenzy —  bouncing from one person’s Hacker News comment to another’s blog post until, in a stupor, we float helplessly toward the brightest light and lay prone in front of it, oblivious to what we were looking for in the first place. This is not how rational people make decisions… Writing code isn’t really about writing. Thinking is the thing that we do. Eventually that gets translated into running code. This is a counter-force against the marketing machine of high opinion technologies. As of 2016, Stack Exchange served 200 million requests per day, backed by just four SQL servers: a primary for Stack Overflow, a primary for everything else, and two replicas.

This is partly because, by its nature, hypermedia navigation requires a client to repeatedly communicate with a server so that it can get all the information it needs. Our responses were bloated and filled with all sorts of *_url hints in the JSON responses to help people continue to navigate through the API to get what they needed. Despite all the information we provided, we heard from integrators that our REST API also wasn’t very flexible. It sometimes required two or three separate calls to assemble a complete view of a resource. It seemed like our responses simultaneously sent too much data and didn’t include data that consumers needed. Something missing or broken? PRs welcome!
