I wrote a script to fetch the scores from CricInfo’s Live RSS feed and post messages to Twitter everytime the score changes.
You can get scores by following indiablues on Twitter.
The code is available here .
UPDATE: Inspired by baggygreen and meninblue, I wrote another script to scrape the comments of off CricInfo’s famous ball-by-ball commentary using BeautifulSoup and post it to Twitter using their API. The only difference is that, I post only the comments mentioning boundaries or Sixes or Outs. Getting all commentary is boring. Anyways, the code is available here.
