Another fantastic post Chris. I love the notion of mentioning a specific part of the text and find it particular useful to link back to sections from my longer posts or parts of my newsletters. I find it interesting to consider alongside Hypothesis and wonder what the different use cases are? I have added the plugin, but found the documentation associated with Kartik Prabhu’s additional code confusing, so left it. Is this what Khurt was referring to? I look forward to seeing where all this grows? Aaron P.S. I thought that Flickr sent webmentions (as it is attached to Bridgy), however I was clearly wrong. Sorry.
