Terrific comment, thank you. First, I've un-minified the Chrome extension code (only added 2kb in size), and it will remain that way going forward. It will take up to an hour for it to propagate to the Chrome Web Store, but the Firefox extension code is un-minified currently : https://addons.mozilla.org/en-US/firefox/addon/kiwi-conversa... (thanks to their review process, which requires it not be minified). The Chrome code is also available on Github : https://github.com/sdailey/kiwi
As for the results vs Reddit check -- maybe Reddit check uses a home-rolled API that crawls more frequently than Reddit's official API? Could you either tweet me the specific links or reply to this comment?
