Before you get too invested in your strategy, I'd like to let you know I think the way you're trying to bootstrap your service is super spammy if your plan is to post these links on HN as often as possible.
You are a bit too aggressive on your trimming: you have trimmed out the chart under the heading "The Right Way to Help Colleagues Excel".
The person below is not wrong... maybe you should add a new path https://beta.trimread.com/hn/${hn_id} and just create a Show HN... I'm sure people would be interested in seeing it.
