colinodell posted that before the blog announcement when we only knew about issue_template.md. It was to point out that you can do this with pull requests as well, not that it was case insensitive.
Do you get many issues that don't use your template because people go to /issues and click the new issue button? When I create an issue with a project, I typically don't a link in readme.md.
This isn't true of GitHub as a whole, and I'm not sure it is true of any part of GitHub. Their team page shows everybody on staff in the order they were hired. Scroll to the bottom and you will see that there is no shortage of white people being hired. https://github.com/about/team
That didn't exactly clear it up for me. Would you mind saying how that clears it up? Does it really mean 1-249 after all?
