Slightly (or completely) off-topic but you really are a taxi driver? I'm curious why you read HN and how you found it.
My work is in a medium many people here would consider to be irrelevant, or even dying.
I'm interested in the world outside my current narrow field of work, I'm interested in how the concepts and ideas discussed here can help my medium stay relevant in this age, and I'm interested in the careers of the future.
My current work won't last forever, I know that, and the more I know now, the better-prepared I'll be.
I was surprised too!
I don't have any down arrows, otherwise I would post code instead of just a suggestion.
I absolutely would love to see the arrows resized when viewing using a mobile device.
