Hat tip to The Guardian for building an excellent web app in 5 days. Proof that rapid web development is possible in large organisations, not only small ones.

The app was written in Django and is hosted on Amazon EC2, the same cloud infrastructure that Mr Monkey employs.

The app is also testament to the power of crowdsourcing - enabling anyone and everyone to contribute to the project. Thousands of people have used the app to analyse the 457,153 PDF pages of MP's expense claims, one page at a time. In the past 48 hours, 136,438 pages have been reviewed. In contrast, The Telegraph has spent at least 7 weeks analysing the documents internally and we don't know what percentage they managed to get through.
