Most of the existing wiki products cannot scale to the size and concurrency that we expect, so we had to design one to work to our demands, using Google's infrastructure. In addition, we believe that tools are most useful when they are easy to use and well integrated into the collaborative development environment. So, we are offering a simple wiki that works well with our existing tools. If you find that your project needs some highly specialized formatting, you can link to Google Page Creator, Google Docs and Spreadsheets, Google Groups, or other pages hosted elsewhere on the Internet.
