Here's me pitching Momentum on IH frontpage:

I used to share long-form articles and questions on IH but didn't get much traction.
Yesterday I lazy-released a landing page to IH. I've simple shared a link to 3 groups here, it took me few minutes.
Originally I planned to write a long press release, but decided to start with something quick to see how it goes.
I've got few comments, replied back quickly and called it a day.
Today I woke up and, surprised, found my post on the IH front-page and 25+ people joined my waitlist!
So lesson here — don't overthink on the early stages. Try every opportunity to promote your product.
I'm building Momentum — a tool for building in public.
Would love to hear your feedback and recommendations.
I'm trying to work out WHEN to get started on PH. I don't have a landing page yet and I read somewhere that you should join approx 30 days before you plan to launch. Any thoughts?
Sorry idk — I'm not good at PH, yet to learn!
Thanks for the tip about groups, I didn't know there were any :D
Thank you, I happy to hear that!
I don't know what are good rules for cross-posting but generally you need to avoid posting in too many groups.
Following conversation here you should try to limit yourself with 2 groups to avoid removal:
