Neat list! I've been privy to a few successful launches, and one the most important learnings was making sure your preparation is sound. Especially for launching on ProductHunt, you need to have your playbook ready and your following needs to be ready as well. When it comes to product launches, there's nothing more frustrating when it's an unorganized, uncoordinated mess and you fail to gain that much needed momentum.

Perhaps that's something you could elaborate more on, or emphasize more.
