A good reply is a mini-post. It earns the click on your profile by being interesting on its own — not by referencing your work.
✦The rule
Never name your offer in a reply. Never plug a link. Just be the most interesting voice in that comment thread.
Wrong: 'Great point! I help people with this — link in bio' Right: 'The thing I'd add: the people who do this best aren't the loudest, they're the most specific. Specificity scales further than volume.'
Reply 2 makes you click their profile. Reply 1 gets ignored.
