What public feedback sources do you check before roadmap decisions?

I’m building PulseBot, an AI product feedback intelligence tool for SaaS teams.

One thing I’m trying to understand better:

before founders or PMs make roadmap decisions, which public feedback sources are actually useful?

Examples:

- Product Hunt comments

- G2 or Capterra reviews

- Reddit or community threads

- competitor changelog comments

- support-style complaints in public

- social posts from frustrated users

I’m especially interested in which signals feel trustworthy enough to influence product discovery, positioning, or roadmap discussions.
