This is not how Cursor got their moment. They built credibility gradually by continuing to develop the product and regularly sharing it in different spaces (Twitter, GitHub, probably elsewhere).

If a project has already been on HN and has set off a flamewar, you don't get a better outcome by submitting the same project under a different URL the following week.

You take the feedback and think about how to improve the product or the messaging, then try again when it's changed enough to be worthy of another shot at the front page.
