Methodology

How to read the Signal Index

The Signal Index starts with public sources and then arranges them in a way that is easier for customers to use. The goal is not to throw every endpoint at you, but to help you move from category to feed to source with less friction.

Source order

Public sources first

  • Official source cards stay visible so you can judge the trust trail yourself.
  • Category pages help you narrow the search before you commit to a feed.
  • Trend pages explain why a source lane matters, not just where it lives.
  • JSON exports exist for customers who want the machine-readable layer.
Moving counts

Why some numbers keep moving

  • The moving counts are a reading aid, not a claim that every provider updates every second.
  • The board uses a rolling pace between official refresh points so the signal layer stays readable.
  • Official source cadence still decides when the underlying picture truly changes.
