Communication at Automattic was roughly broken down as follows: 1. Blogs (P2): 75 percent 2. IRC: 14 percent 3. Skype: 5 percent 4. E-mail: 1 percent Of course, since Skype and e-mail were private, these are just guesses. Most of the uses of e-mail, as low as it was, were for notifications about new posts or comments on P2s.
