3 Days until launch, any last-minute advice?

Hey, here's Marin, CEO and co-founder of Omnisearch. We're going live on Product Hunt in just 3 days (October 10th). Even though it's the third launch for me, I'm eager to hear any last-minute advice fellow PH'ers might have to make it even more successful. What are some less frequent or counterintuitive pieces of advice that worked well for you?
