I think the "how I use my machine" vs "how my machine affects other developers" distinction is a useful one.

The line gets fuzzy here because there are configuration options that will affect other developers who pair with you or try to help you through a problem. If you're not using `--binstubs`, your partner will get frustrated when all their commands result in "try using bundle exec, wah wah."

I'd like to drop the `--binstubs` line here and start a larger discussion elsewhere about standardizing configuration.
