Comments

• Match the subreddit's tone and norms
• Add value: share experience, provide data, ask good questions
• Don't self-promote unless the subreddit explicitly allows it
• Read the full thread before replying — don't repeat what's said

Formatting

• Use markdown (Reddit supports it natively)
• Break long responses into paragraphs with headers
• Quote the specific part you're responding to

Etiquette

• Don't edit comments to change meaning after replies
• Acknowledge when wrong — builds credibility
• Avoid sarcasm that could be misread

Gotchas

• old.reddit.com selectors differ completely from new.reddit.com
• Rate limiting on comments: ~10 min cooldown for new/low-karma accounts
• Some subreddits require minimum karma to post
• Embed workflows use old.reddit.com — navigate there first
