I really disagree with the general sentiment of this post, and very much agree with the original "Dear GitHub" letter. The product needs a lot of work, and that I couldn't address these problems while I was there really, deeply depresses me.
Issues hasn't been touched since I shipped the third large iteration a year and a half ago. It was never intended to be a finished product at that point; it was intended to evolve quite a bit from that initial vision. There's a lot of pain that open source developers and private source developers face today, and I really hope we all can start seeing that pain in our community eased soon.
