User survey

Hi users. A quick survey:

1. How did you discover git-credential-oauth?
2. How did you install git-credential-oauth?
3. Do you authenticate to any Git hosts outside GitHub?
4. What's your credential.helper configuration? Run `git config --get-all credential.helper` to check.
5. What problem did git-credential-Oauth solve for you?
6. Any ideas for improvements?
