I wrote most of the code in November and submitted it for review in December. It was first tested by a guy in Pakistan, and with his feedback I made changes. Then it was tested by a guy in Boston. Once again, feedback and changes. Finally, it was tested and approved by a guy in Austria, and promoted to full project status by a guy in Germany.
When was the last time you collaborated with 7 people from 6 different countries, ad hoc, over a two week period, to bring forward some common work?
This is an amazing world we live in.
