>Responding to feedback from the ‘wrong’ customers kills so many products/startups.
That's something I wonder about with Show HN. Aren't many of us on HN inherently the 'wrong' customer for any product or service that aspires to be mainstream?
Famously, for example, 10 years back, some of the comments when @dhouston submitted "My YC app: Dropbox - Throw away your USB drive" [1] pretty strongly indicated 'wrong' customer.
I won't pull out the comments, because: 1. I don't want to make it personal & 2. It's with the benefit of hindsight.
