  19      * Python wrapper around the Python API (Python-Twitter): http://code.google.com/p/python-twitter/

  22     @TODO:
  23      1. Better caching for the displayed tweets (because of limits: http://apiwiki.twitter.com/Rate-limiting) in memory of filesystem
  24      2. Authentication without cleartext passwd (maybe http://apiwiki.twitter.com/OAuth-FAQ)
  25      3. Better error handling for the urllib, not depending on sys and socket stuff
  26      4. Output of tweets as html (not wiki like now) and using some regular expressen to create working html links (for links and twitter references)
