Quick answer
YouTube comments are signal when they add constraints the video skipped (version, OS, edge case, “this broke my prod”). They are noise when dominated by memes, self-promotion, or off-topic politics. Prefer timestamped technical comments and repeat patterns across multiple videos.
Best for: visual products (devtools with demos, data products with walkthroughs) where setup details leak in comments.
