GitHubber here, we'll follow up on this with Pete. We think one of our replies was missed along the line. Thanks for letting us know.
It seems he unfortunately missed one of our replies and therefore considered us unresponsive.
Given the other posts, it seems there might just be some confusion that needs clearing up; for that, we'll have to see if our blogger posts anything more.
