I considered doing the same thing myself, as a way to start random conversations with local coders &amp; startup folks.<p>I often work from cafes or public places, and I figured it&#x27;s a way of inviting coders who walk past to say &quot;Hey, I saw your sticker... do you read Hacker News?  I&#x27;m working on a startup too.  What are you working on?&quot;
