mail lists

recently, I begin to join all kinds of mail lists: such as linux kernel, gstreamer, arm linux, openmoko, android... all of them are opensources, and mail lists are their most used way to communicate with each other, discuss the problems they encounted, and of course, their contributions to the opensource project.

why I keep so many list?
1 I could get the latest info about the projects I interested.
2 I want to find something to research in. after reading the mail lists for a while, I think I could find something I could get in. God bless the time would be too long.

OpenMoko is the project I want most, cau's it is about the smart phones, which is most related to my current job. Though my boss do not think it will be a strong competitor in all kinds of linux phone associations.
