Respectfully Jono, I think your reply is symptomatic of the issues at the heart of the matter. GitHub is, whether it expected to be or not, whether it wants to be or not, now at the heart of the OSS community. For the "Director of Community" at a company which plays such an important role in the OSS community, which itself plays an enormously important role in the broader software and civic communities and is populated by abnormally high numbers of passionate and talented contributors, to respond to a HN story with such a high profile by:
1) apologizing for being new
2) extending borderline patronizing praise (the OP likely wanted a response to the issues put forth, not your approval)
& 3) a promise, which you can't necessarily keep, to put eyes on the issue instead of speaking to the issues raised directly.
It's not what I would expect from someone in that role at that sort of company. It's, unfortunately, what I would expect from a company that had the sort of issues raised by the OP.
