Ask HN: Why? (Also, thank you)

I first want to say thank you to the HN community. In a constant search for Truth I have always found HN comments to be my "center". I feel HN to be Honest and Good amuck the Falsehood and Agenda that I find elsewhere in life. So here is my question: why do you share here and what makes HN different? Cheers to a wonderful 2018 and a fulfilling 2019.
