We're not trying to compete for attention in the social web. Part of that is reflected in our involvement with the W3C Open Annotation Working Group (http://www.w3.org/community/openannotation/). While Hypothes.is may be one place to publish, the goal is to provide better linking and referencing tools to facilitate aggregators and plugins that can bring the conversation back to the source material. In other words, to bring this conversation on HN into the RWW frame and vice versa and to allow better quoting and transclusion between these content silos.
