During my first job, my boss introduced me to HN. I doubt I would've found it so soon otherwise, as the only other person that knew about it before I mentioned it is someone I only met this year.

My first boss was a great guy to work with and I'm grateful he told me about it. Even though I learned a lot from him professionally, the impact of that one-time five-minute conversation about the site might have added up to more over the years.
