I suspect that next, with a tad bit of parsing using microformats, you can add some display elements to your webmentions to indicate the author, their url, date/time, and actually include the reply text to have a better UI for them.
Indeed, my current implementation just shows the validated Webmention links, and my plan is to slowly enhance them over time. I think, just like in the case of the basic Webmention support, Will Norris may have my back again and have already done the heavy lifting for Microformats and Go.
