GOPATH was weird to get used to at first, but I gave in and I actually store all my projects, even non-go projects, in the same folder hierarchy now. It has made me much more organized. In fact here's a zsh function I have for cloning new projects into that structure. It makes my home directory much less of a mess.

  gclone() {
  		dir=$(echo $1 | sed 's/^http\(s*\):\/\///g' | sed 's/^git@//g' | sed 's/\.git$//g' | sed 's/:/\//g' )
  		git clone $1  "$HOME/src/$dir"
  		cd "$HOME/src/$dir"
  }
