Quote of Ted Ts'o:
One of the primary reasons why I started the kernel summit ten years ago was because I've found that people work better after they have had a chance to meet each other face to face. If you only know someone via e-mail, it's lot easier to get into flame wars. But after you've met someone, broken bread and drunk beer with them, it's easier to work with them as a colleague and fellow developer. While the Linux Kernel development community has grown significantly since March, 2001, this principle still holds true.
