“Share” seems to be one of the buzzwords nowadays. With http://dotfiles.org/, now you can share your dotfiles configuration, such as:
.vimrc
.screenrc
.bashrc
.zshrc
.irbrc
.Xdefaults
.conkyrc
.bash_profile
.xinitrc
.emacs
Pretty unique… I just remember when my friend introduced me to a colorful ViM by changing the .vimrc. That was the first time I felt in love with ViM.
