WE ROLLED OUR OWN DOCUMENTATION SITE

Tangled decided to build its own documentation site using Pandoc to meet specific requirements like no JavaScript, low complexity, and easy styling. Its team used Pandoc's "chunkedhtml" output to convert a single Markdown file into a static site, using an autogenerated table of contents and a JavaScript-free collapsible sidebar via the new popover API. For search, they used a Google redirect and provided a single-page version for browser-native Ctrl+F functionality.

THE QUESTION YOUR OBSERVABILITY VENDOR WON'T ANSWER

In observability, vendors strong-arm clients and costs constantly escalate, forcing users to act as cost police. The core issue is vendors' willful ignorance of how much observability data is waste. An average of 40% of observability data is not used.
