This is a horrifically dumb article. If you care about the first day, you didn't launch a startup, you launched a project. Submitting an article to Hacker News isn't a launch strategy, it's showing off a cute project you did.

A startup is something you fully commit to until you're convinced you tried every reasonable permutation in a scalable market opportunity.

The average startup takes 7 years to get to liquidity. That's 2,520 days. You got one day in before throwing in the towel.
