In 2014, I posted a chrome extension called UX Check (http://uxcheck.co) as a Show HN. It didn't get any traction, but a month later, somebody reposted it and it hit the front page. I received an amazing amount of encouragement and support, with tons of great feedback. I rolled a lot of that feedback into an update a month or two later, and within 6 months, I had decided to leave my job to work full time on building a related product. Still working on that product and not ready to share it yet, but thank you to everyone!
