title: How to map Twitter directed-graph/topology?
body: <p>For my research, I want to use some data that can capture twitter users following each other . I want to represent this relationship in a big directed-graph. If you think about this graph it's probably very huge, I want to generate it and perhaps store it in adjacency-matrix format.</p>
  
  <p>However when I tried to make use of Twitter's API, there are some useful methods like GET followers, GET friends I can use. But it has 150query/hour limit. At that rate, I would never finish crawling Twitter and generate a good enough direct-graph.</p>
  
  <p>Is there a better way of doing this?</p>
