title: Getting started with Twitter API
body: <p>I'm developing an app whereby users tweet me (@Eamorr) and I respond with the phone number of the nearest business based on the geolocation embedded in the tweet.</p>
  
  <p>I'm not really sure where to start and thought I'd ask the community.</p>
  
  <p>I'd like to make this as real-time as possible - i.e. where there is minimal delay between the user tweeting @Eamorr and them receiving the phone number. Is node.js a good solution for this?</p>
  
  <p>Btw, my server runs php, but I'm language agnostic, so any suggestions are most welcome.</p>
