Last week, after a long Halloween day, I scrolled through my Reddit subscriptions and read a familiar headline: You can't impress developers. So don't try. My post from 5 years ago hit the front page of HN and was cross-posted to /r/programming.
I didn't read all the comments or respond, but I understand why many people disagreed. The title was purposefully a bit click-baitish, but I still agree with my core viewpoint: Don't focus on impressing other developers. Focus on your users.
We have a hackathon this week, where we will all have the chance to impress each other, and I'm certain we will. The trickest code won't win, but the trickest feature might.
