My .bash_profile

.bashrc

# if .bash_profile on OS X is not sourced, do `ln -s .bash_profile .profile`

alias wow='git status'
export GIT_EDITOR=vim
export VISUAL=vim
export EDITOR=vim
export LC_ALL=C

# brew install bash-completion
if [ -f `brew --prefix`/etc/bash_completion ]; then
    . `brew --prefix`/etc/bash_completion
fi

very nice gist!
I propose improvements:

alias nah='git reset --hard;git clean -df'
alias vi='vim'
# better locale, present on all EC2 amis, supports characters with umlauts, usually has no conflicts with C etc
export LC_ALL=en_US.UTF-8
