Ask HN: As a developer, I care about ____ when intro'd to a new technology

Hi HN, I started thinking through how URX (YC S13) can make our developer onboarding flow better. Right now, I'm thinking through the question, "As a developer, what are the 3 things I care most about when being introduced to a new technology?" After a few minutes, this is what I came up with: 1) Why does this matter to me? What would I have to be trying to build for this to be valuable? 2) What should I do with it? What's a tangible context that I'd use this software? 3) How do I try it, now? Where do I start? HN, what do you think? -jmilinovich
