Please read the comments above about the multiple ways that Kobble can be used. Our use of gists for openly sharing content was entirely intentional.
Having read through the information on your site now it's been updated, it's much clearer than it was before. I feel like it should have been closer to this before submitting to HN, but the changes ("Gists are not private, and are suitable for content that you want to share", "control" rather than "own") are definitely a step in the right direction.
